When you buy a retail computer CPU, it usually comes with a standard cooler. However, most enthusiasts find that the stock cooler just does not cut it in terms of performance. So, they often end up getting a more advanced cooler that better suits their needs. Choosing the right cooler isn't a one-size-fits-all deal – it is a bit of a journey. You have to consider what you need, what you want, your budget, and how much space you have in your setup. All these factors come into play when picking out the perfect cooler.

When it comes to high-performance coolers, Noctua is a name that frequently comes up among enthusiasts. Known for their exceptional build quality and superb cooling performance, Noctua coolers have been a favorite in the PC building community for years. A typical Noctua cooler will be punctuated by incredibly quiet fans and top-notch cooling efficiency overall, which has made them ideal for overclockers and builders who want to keep their systems running cool and quiet.

In this review, we'll be taking a closer look at the NH-D15 G2 cooler, the successor to the legendary NH-D15. This cooler comes with a hefty price tag of $150 but promises to deliver the best performance that an air cooler can currently achieve. The NH-D15 G2 is available in three versions: one standard version as well as two specialized variants – LBC (Low Base Convexity) and HBC (High Base Convexity). These variants are designed to make better contact with specific CPUs; the LBC is recommended for AMD AM5 processors, while the HBC is tailored for Intel LGA1700 processors, mirroring the slightly different geometry of their respective heatspeaders. Conversely, the standard version is an “one size fits all” approach for users who care more about long-term compatibility over squeezing out every ounce of potential the cooler has.

Continuing our ongoing look at the latest-generation ATX 3.1 power supplies, today we are examining Cooler Master's V Platinum 1600 V2, a recent addition to the company's expansive PSU lineup.

The V Platinum 1600 V2 is designed to cater to top-end gaming and workstation PCs while offering maximum compatibility with modern ATX directives. And while it boasts a massive 1600 Watt output and a long list of features, the V is a workhorse of a power supply rather than a flagship; Cooler Master is aiming the PSU at budget-conscious users who can't justify spending top dollar, but whom none the less need a powerful and relatively efficient (80PLUS Platinum) power supply.

So often we see PSU vendors go for broke on their high-wattage units, since there's a lot of overlap there with the premium market, so it will be interesting to see what Cooler Master can do with a slightly more modest bill of materials.

As mainstream power supplies continue to make their subtle shift to the ATX 3.1 standard, the pace of change is picking up. Already most vendors offer at least one ATX 3.1 unit in their lineups, and thanks to the relatively small set of changes that come with the revised standard, PSU vendors have largely been able to tweak their existing ATX 3.0 designs, allowing for them to quickly roll-out updated power supplies. This means that the inflection point for ATX 3.1 as a whole is quickly approaching, as more and more designs get their update and make their way out to retail shelves.

Today we're looking at our first ATX 3.1-compliant PSU from Corsair, one of the industry's most prolific (and highest profile) power supply vendors. Their revised RMe line of power supplies are aimed at the mainstream gaming market, which is perhaps not too surprising given how important ATX 3.1 support and safety are to video cards. The RM750e model we're looking at today is the smallest capacity for the lineup, which stretches from 750 Watts up to a hefty 1200 Watts.

Overall, the RM750e is built to meet the demands of contemporary gaming systems, and boasts a great balance between features, performance, and cost. It is an 80Plus Gold certified unit with modular cables and PCIe 5.1/ATX 3.1 certified, offering a single 600W 12V-2x6 connector. We will explore its specifications, construction, and performance to determine its standing in today’s market.

In response to the increasing popularity of compact and portable gaming PCs in the past couple of years, we've seen several PC peripheral manufacturers release larger collections of SFX form factor cases and power supplies. Chief among these has been Cooler Master, where the prolific PC part vendor recently expanded their SFX series to include ATX 3.0-compliant PSUs. This has finally given the company a modern, miniature platform that can drive the latest NVIDIA video cards.

Today we're looking at Cooler Master's V850 SFX Gold, which represents a more budget-friendly option in the SFX power supply market compared to their previously reviewed V1100 SFX Platinum. The SFX Gold series includes four models, ranging from 550W to 850W, with the 850W unit that we are reviewing today being the most potent. This 850-Watt power supply carries an 80 Plus Gold certification and is designed for high-performance gaming and workstation builds. As the top-tier model in the SFX Gold series, it offers substantial power output for an SFX unit and maintains ATX 3.0 compliance, including a 12VHPWR connector in a compact SFX format.

Just several years ago, we were impressed to witness a 2,000W power supply for mining systems at Computex. But with arrival or AMD's Ryzen Threadripper WX and Intel's Xeon W-3400-series – CPUs that can devour all the way to 900W under heavy loads – as well as NVIDIA's GeForce RTX 4090 graphics cards (or, well, H100 PCIe for AI), 2,000W PSUs are no longer entirely overkill. As new processors have raised the bar on power consumption, so has the bar been raised on PSUs themselves. as evidenced by this year's show, with several power supply manufacturers showing off new extreme PSU designs that go as high as 2,800W.

To that end, I will begin the story from the least 'extreme' PSU that I saw at Computex and this is Seasonic's Prime PX-2200 80+ Platinum-badged ATX 3 PSU. The unit handled a custom-built AMD Ryzen Threadripper Pro 7995WX-based PC with 256 GB DDR5-4800 memory and four Gigabyte GeForce RTX 4090 graphics cards without breaking a sweat at the trade show.

It is noteworthy that the Prime PX-2200 has only one 16-pin 12V-2x6 power connector for graphics cards, so Seasonic used adapters to power three out of four RTX 4090 boards.

Moving on to a more powerful PSU, which is Enermax's Platimax 2400W 80+ Platinum-rated ATX 3.1 power supply. This one has two 12V-2×6 auxiliary power connectors for graphics cards, which is more than enough for an extreme gaming system. Enermax did not showcase this one in action at Computex, perhaps, because it is almost half of a year away and yet has to pass all the necessary tests.

The Enermax Platimax 2400W is set to enter mass production this December and will be available for $499, according to the company.

But what is 2,400W, if you can get all 2,800W? Well, Super Flower's Leadex SF-2800F14HP 80+ Platinum-badged ATX 3.1 PSU can deliver 2,800W to a high-performance CPU and four graphics cards over five voltage rails. This power supply is well beyond what even a high-end desktop needs, and seems aimed more at workstation-style AI systems for research or on-prem inference. This one is expected to be available later this year for around $599, according to a representative at the booth.

Gallery: Super Flower Leadex SF-2800F14HP ATX 3.1 PSU

It goes without saying that these extreme power supplies have a rather limited market. Not only because of the small base of systems that could ever need a PSU that could be measured as a multiple of horsepower (745W), but also because of outright mains compatibility – the standard US 15A/120V outlet can't drive much more than a 1600W PSU. So power supplies like these are only readily usable in Europe, and in locations in the US with non-standard outlets. Then again, if you need a 2,800W PSU, you can probably afford the electrician needed to get one wired up.

While the market for high-end CPU coolers has decidedly shifted towards closed-loop all-in-one liquid coolers over the last several years, air cooling remains alive and well. Even at the high-end, there are still further improvements and innovations being made, such as DeepCool's vapor chamber-based tower cooler, which was demonstrated at Computex.

Named the Assassin IV VC Vision, DeepCool's design is an advanced concept vehicle that equips a tower cooled with both a vapor chamber in the base as well as has an LCD pad on top for extra flourish. The vapor chamber is said to increase the cooling capacity by 20W, adding a bit more of an edge to an already very powerful tower cooler design.

While we expect this one to come to market eventually, don't be surprised if both vapor chamber and the screen to land on other products together or separately. For example, the massive DeepCool Assassin IV VC Vision has a more compact brother that has a screen and a vapor chamber.

The unit builds on top of the already monstrous DeepCool Assassin IV that comes with seven 0.6-mm heat pipes and can mount up to three 120/140mm fans, depending on installation (one is magnetically attached). With a weight of 1.575 kilograms – almost entirely copper and aluminum – this one is already good enough to cool down even the highest-performing CPUs.

DeepCool is currently trying to figure out recommended pricing for its Assassin IV VC Vision cooler, but the original Assassin IV costs $99.99, so expect the unit with a vapor chamber and a screen to build on top of that.

With the highly integrated nature of PCs these days, the Mini-ITX form-factor has become a very viable option for high-performance gaming system. With plenty of motherboards available for both AMD and Intel's latest platforms, equipping an ITX system with a CPU is easy enough. But the small size of the form factor means that housing an ultra-wide flagship-level graphics card remains an issue. For this year's Computex trade show, Antec was showing off their solution to the problem of giant video cards: the Performance 1M case, a Mini-ITX case with a separate chamber just for a large video card.

Antec's Performance 1M is a dual-chamber Mini-ITX chassis that splits off the video card from the rest of the system. The primary chamber houses a Mini-ITX motherboard and an SFX power supply, while the secondary chamber houses a huge graphics card. Notably, the two chambers are bridged using a PCIe riser cable, allowing the motherboard chamber to be far shorter than even a half-height PCIe card, while the video card chamber can hold a triple-slot video card parallel to the motherboard chamber, cutting down on wasted space. For Antec's Computex demo, the company had a triple-slot ASUS GeForce RTX 4090 installed to showcase how this worked.

Antec's decision to allocate most of the case's volume to th video card chamber does come with a slight catch, however: it doesn't leave much space for a CPU cooler in the motherboard chamber. The short motherboard chamber means that system builders will have to use a low-profile cooler; these are readily available, but it does leave less thermal headroom overall for high-end CPUs. So there are still trade-offs for being able to accommodate a high-end video card.

Otherwise, the Performance 1M chassis from Antec look very stylish and are traditionally well built from stainless steel and aluminum. The chassis can be equipped with two 120-mm or two 140-mm coolers for extra airflow (which will help performance), one 2.5-inch SATA SSD, and even some RGB bling. To make the PC built inside a Performance 1M case more convenient to use, there are two USB Type-C ports on the front.

Of course, housing a GeForce RTX 4090 graphics card in a Mini-ITX chassis has its peculiarities when it comes to dimensions and Antec's Performance 1M measures 424×175×260mm, which is pretty large. On the other hand, for an ultra-high-performance gaming system, this is pretty compact.

Antec's Performance 1M Mini-ITX chassis will be available in gunmetal gray and matte black colors sometimes later this year. Pricing is something that the company is thinking about now, though keep in mind that we are talking about unique premium products.

Many companies showed off a range of concept designs during Computex 2024, but perhaps Noctua had one of the coolest. Noctua, primarily known for its air coolers, had a pumpless prototype that showcased Thermisiphon cooling. It looks like a conventional AIO cooler on the surface but is much more efficient, cooler, and quieter than traditional water coolers.

Touching quickly on Thermosiphon cooling, it uses the natural laws of thermodynamics to use heat (the CPU) as a source to turn the liquid to the top, evaporating through the system. This evaporated liquid rises and is pushed into the condenser (radiator), which, in the case of Noctua's cooler, is cooled by fans and turned back into liquid, which then flows back toward the CPU. Not only does Theromsiphon technology use gravity to help aid the flow of liquid, but it is also a highly efficient way of distributing heat as vaporization can absorb heat better, and it doesn't feature any moving parts in the mechanism, aside from the fans, of course.

As with traditional AIO CPU coolers, Noctua's Thermosiphon design has a 240mm radiator with a pair of 120cm Noctua fans, which cools the vapor down and sends it back to the evaporator. While this isn't a new concept and vapor chamber cooling has been used for many years in CPUs and even laptop coolers, Thermosiphon is certainly a technology Noctua thinks it can leverage to ensure better cooling performance and robust reliability.

Speaking to Noctua at Computex 2024, they informed me of the benefits and pitfalls of the Thermosiphon technology. In terms of the pros, Thermosiphon cooling in itself has no moving parts, which not only improves reliability but also means there is less to go wrong. Another positive is that even the quietest AIO CPU coolers can be quite noisy, as the water pump that circulates the fluid can cause vibrations, which in turn makes noise. The biggest drawback of implementing Thermosiphon cooling for PCs is that conventional tubing can wear out over time. While adding metal tubing would last longer, it's not flexible, although Noctua said they have discussed this with system integrators.

Although Noctua's Thermosiphon is currently just a proof of concept and sis in the early development stage, there's no launch date or indication it will hit the market. It's an interesting design, and we hope it does eventually come to market.

Trade shows like Computex always bring out their fair share of oddities, and this year was no exception, with one of the highlights being a Corsair PC case with no fewer than 24 fans.

As one of a handful of companies offering really big desktop PC cases, Corsair was demonstrating its new creature: the 9000D Airflow. At 90 liters in volume – which is twice the size of regular PCs and 1.5x the volume of a typical car gas tank – the colossal case is bigger than ever. It's so big, in fact, that it can house two systems: a full-size ATX (or smaller) system, as well as a separate Mini-ITX system.

Gallery: No, It Does Not Fly: Corsair Has a PC Chassis with 24 Fans

The most eye-catching aspect of this PC case (besides its large size, of course) is that it can house as many as 22 fans in addition to two liquid cooling systems. As the name of the 9000D Airflow implies, all of those fans are meant to create as much airflow as possible. And yet, because there are so many fans inside, they do not have to run at a high RPM to move the requisite amount of air, so the 9000D Airflow is quieter than its size otherwise lets on.

To simplify installation of all these fans, the chassis consists of adjustable mounting points on a sliding rail, making the case versatile for any build requirements. The 9000D includes two InfiniRail systems, one at the top (holding six fans) and one at the front, each capable of holding up to eight 120mm fans. Adding fans on the sides and rear increases the total to 24. For those using 140mm or 200mm fans, the InfiniRails can be adjusted by unscrewing and repositioning them based on marked guidelines, allowing for a customized setup despite fitting fewer larger fans. The flexibility of the InfiniRail system enables unique fan placement, enabling the freedom to tailor the cooling configuration to specific needs.

The case design also includes 30mm of clearance behind the motherboard for efficient cable management, making it well-suited for creating clean, organized, and powerful builds.

Besides its may fans, the 9000D Airflow also offers 11 drive bays, plenty of front I/O ports (four USB Type-A, two USB Type-C, audio connectors) with RGB lighting controlled through the iCue Link system. The spacious design allows for comprehensive component compatibility and expansion.

Corsair's Airflow 9000D will be available later this year.

Enermax, established in 1990, is a renowned Taiwanese company in the PC hardware industry, particularly recognized for its innovative power supply units (PSUs), cooling solutions, and PC cases. Over the years, Enermax has built a reputation for engineering reliable, high-performance PSUs that primarily target enthusiasts and professional users. Their commitment to quality and technological advancement has kept them at the forefront of the industry, constantly evolving to meet the demands of the ever-changing tech landscape.

In this review, we are looking at the latest addition to Enermax's impressive PSU lineup: the Revolution D.F. 12 750W PSU. This is the second ATX 3.1-compliant power supply to arrive in our labs, and, broadly speaking, illustrates how we're approaching the inflection point for PSU vendors to update their designs for Intel's revised PSU standard.

As for the Revolution D.F. 12 itself, Enermax's new PSU pursues a balanced design, meeting modern gaming PCs mid-way with good conversion efficiency and an overall robust power delivery system. With features like fully modular cables with per-wire sleeving, a dynamic hybrid fan control for optimal cooling, and advanced topologies, the Revolution D.F. 12 750W is primed to deliver on both reliability and performance. We will delve into its specifications, build quality, and performance metrics to see if the new unit lives up to Enermax's esteemed legacy.

In recent months, Frore Systems has been turning heads with their fanless solid-state air cooler technology. The AirJet, as it's come to be called, was previously shown off at CES this year; and for Computex, the company is back with a fresh round of demonstrations.

For the show, Frore has a number of demonstrations running in a fairly large showroom. The company is looking to address a wide range of products, from tablets to notebooks to small PCs, as well as embedded tablets. But there were two showcases in particular that caught my immediate attention: a Samsung Galaxy Book with and without Frore's AirJet, and an 8 TB Sabrent SSD in an external enclosure.

The Samsung Galaxy Book 2 Pro is an ultra-thin notebook that is normally cooled by a fan that, as argued by Flore, does not do its job properly. According to the company, the stock laptop only has enough cooling capacity to sustain 12W heat/power before it hits Tmax, whereas a retrofitted version with Frore's AirJet installed allows it to hold steady-state operation at 16W – and consequently delivering higher performance. In terms of Cinebench R23 multi-threaded results, we are talking about 5330 points for the modded notebook, versus 4255 for the off-the-shelf Galaxy Book 2 Pro.

The potential use cases for Frore Systems's AirJet solid-state cooling technology do not end with CPUs, either. As mentioned previously, the company is also demonstrating the AirJet Mini on Sabrent 8TB SSDs in Orico external enclosures, showcasing the advantage of the silent active cooler over passive cooling. The passively-cooled drive reached 62°C and leveled out at 1,320 MB/s due to thermal throttling. In contrast, the AirJet-cooled drive maintained a temperature of 42°C and achieved a considerably higher performance of 3,016 MB/s.

According to Frore, this significant improvement in both temperature and performance has already led to one major external SSD vendor adopting AirJet technology to improve the performance of their drives. Unfortunately, Frore isn't naming any names, only stating that it's a "big name."

Now, Frore's AirJet Mini and Mini Slim coolers can dissipate up to 5W of power each, and can be combined in to larger blocks of up to 5 coolers (we are talking about announced solutions, technologically scaling could he higher, but this is an entirely different conversation). So the technology does have some scalability limitations that makes it best-suited for lower-power devices. None the less, removing 25W of thermal energy from a modern laptop without a fan can make a huge difference in the performance of these normally passively-cooled devices.

Of course, the main goal for these Computex demos is far more than just showing off AirJets to the public; what Frore would really like to do is to land a deal for its solid-state cooling solution with a major PC vendor (e.g., Apple, Samsung, etc.). Though to do that, Frore has to pass qualification tests and ensure availability of its products, which is something the company says it's currently working on. Meanwhile, from performance point of view, especially given their dimensions, AirJets look very impressive.

Founded in 1980 and headquartered in Taiwan, Sunon (aka Sunonwealth Electric Machine Industry Co., Ltd.), stands out as a prominent global producer of fans, blowers, and thermal management systems. The company has made a name for itself in the fan industry with a comprehensive product line that includes DC brushless fans, micro blowers, CPU coolers, and various other cooling technologies. They are one of the oldest and most renowned fan manufacturers on the world – and not just for PC applications, but for just about anything in need of something smaller than a ceiling fan, spanning from IT to automotive and industrial sectors.

Within the PC space, the company is best known for its proprietary MagLev (Magnetic Levitation) technology, which uses magnetic forces to levitate the rotor shaft, drastically reducing friction and wear. This innovative design improves the durability and performance of their fans, particularly in reducing operational noise and improving high-temperature performance. Sunon introduced the patent and their first MagLev products all the way back in 90s.

The 120mm Sunon MagLev fan that we are reviewing today – MFC0251V2-1Q02U-S99 – is a new, high-performance fan engineered primarily for PC applications, with an emphasis on longevity and functionality. It features Sunon's advanced Vapo-Bearing MagLev Engine, which allegedly ensures a quieter operation and longer lifespan by minimizing friction. This particular fan has a maximum speed of 1900 RPM and all of the bells and whistles of advanced cooling fans, including a wide range PWM speed control (10-100%).

Distinguished by its crisp white color and unique frame design, this fan is aimed PC builders going for a clean and modern aesthetic. The "gaming" designation by the manufacturer clearly divulges their intentions regarding their targeted audience. By default, these fans have both a 4-pin connector and also a Molex connector for their direct connection to the PSU.

Fan Testing Methodology

We are testing fans using an Extech HD350 differential manometer, an Extech AN200 velocity meter, and a custom 3D printed apparatus designed for this specific purpose. The apparatus features a simple but effective shutters mechanism that allows us to test the unobstructed (maximum) volume flow of a fan, the fully obstructed (maximum static) pressure of the fan, and multiple points in between, allowing us to compose the actual P-Q performance chart of any fan. The RPM reading is taken with the fan unobstructed (maximum flow), as the fan speed varies depending on the airflow impedance in conjunction with the design of the fan’s blades.

For noise measurements, we are using an Extech HD600 high sensitivity SPL meter. The noise of the fan is measured from 15 centimeters away, not one meter as IEC certifications require, as that would be far too great a distance to measure differences between nearly silent products. Note however that we are measuring the noise level of a fan with its flow unobstructed and the fan, to the best possible degree, uncoupled from the environment. The addition of fan grills, the installation on a cooler, and any other form of obstruction will increase the generated noise, as both aerodynamic and vibration noise will be added into the environment.

Test Results & Conclusion

The Sunon MFC0251V2-1Q02U-S99 is a robust performer across the entirety of the performance chart. At its maximum speed of 1900 RPM, it offers an airflow of 58.9 CFM and a static pressure of 2.48 mmH₂O. However, that performance comes with a noise output of 41.3 dB(A), which is quite noticeable and, in most cases, not really ahead of its competition. When compared to the Corsair ML120, another fan with a magnetic levitation engine, the Sunon model tends to offer significantly better performance by running about 300 RPM faster while generating about the same level of noise.

Overall, Sunon's 120mm MagLev fan stands out as a high-quality part, and better still it's priced competitively at around $11, offering substantial value for those looking for robust cooling solutions within budget constraints. When it's used correctly, the fan easily competes with, and generally outperforms, the best 120 mm products currently available – albeit not immensely so.

However "used correctly" is the operative term, as the MagLev engine makes the fan particular about its orientation. In short, these fans are not meant to be installed with the engine facing upwards, as this can jeopardize the integrity of the Vapo mechanism. As a result, Sunon's MagLev fan is really only good for horizontal airflow – front and back air intake/exhaust – and shouldn't be used for vertical airflow at the top and bottom of computer cases.

Despite that, the 120mm MagLev fan does excel when it's in its niche, especially at its price. The biggest hurdle, in that case, is just acquiring a fan, as Sunon is primarily geared up to target the bulk OEM market and doesn't sell their fans in individual retail units. So prospective buyers will need to skip the Neweggs and Amazons of the world, and look instead at electronic and industrial suppliers like Digikey and Mouser.

As modern high-performance CPUs generate more heat, there's been a noticeable increase in the demand for powerful air coolers capable of managing these thermal challenges. Traditional stock air coolers, while sufficient for regular use, are typically designed to be cheap and relatively compact, leaving further improvements to noise control and peak cooling efficiency on the table. This gap has long prompted advanced users and system builders to opt for high-quality aftermarket coolers that designed to better handle the heat output from top-tier processors.

Known for their innovative approach to PC hardware, Arctic Cooling has stepped into this competitive market with a product aimed at delivering effective cooling at a very low retail price. The Freezer 36 A-RGB, a dual fan tower cooler, is designed to support the cooling demands of the latest CPUs while also offering customizable RGB lighting for visual flair. This review will explore the features, performance, and value of the Arctic Cooling Freezer 36 A-RGB, comparing it with other leading products in the market to see how it stacks up in providing efficient and effective cooling for modern CPUs.

Founded in 1980 and headquartered in Taiwan, Sunon (aka Sunonwealth Electric Machine Industry Co., Ltd.), stands out as a prominent global producer of fans, blowers, and thermal management systems. The company has made a name for itself in the fan industry with a comprehensive product line that includes DC brushless fans, micro blowers, CPU coolers, and various other cooling technologies. They are one of the oldest and most renowned fan manufacturers on the world – and not just for PC applications, but for just about anything in need of something smaller than a ceiling fan, spanning from IT to automotive and industrial sectors.

Within the PC space, the company is best known for its proprietary MagLev (Magnetic Levitation) technology, which uses magnetic forces to levitate the rotor shaft, drastically reducing friction and wear. This innovative design improves the durability and performance of their fans, particularly in reducing operational noise and improving high-temperature performance. Sunon introduced the patent and their first MagLev products all the way back in 90s.

The 120mm Sunon MagLev fan that we are reviewing today – MFC0251V2-1Q02U-S99 – is a new, high-performance fan engineered primarily for PC applications, with an emphasis on longevity and functionality. It features Sunon's advanced Vapo-Bearing MagLev Engine, which allegedly ensures a quieter operation and longer lifespan by minimizing friction. This particular fan has a maximum speed of 1900 RPM and all of the bells and whistles of advanced cooling fans, including a wide range PWM speed control (10-100%).

Distinguished by its crisp white color and unique frame design, this fan is aimed PC builders going for a clean and modern aesthetic. The "gaming" designation by the manufacturer clearly divulges their intentions regarding their targeted audience. By default, these fans have both a 4-pin connector and also a Molex connector for their direct connection to the PSU.

Fan Testing Methodology

We are testing fans using an Extech HD350 differential manometer, an Extech AN200 velocity meter, and a custom 3D printed apparatus designed for this specific purpose. The apparatus features a simple but effective shutters mechanism that allows us to test the unobstructed (maximum) volume flow of a fan, the fully obstructed (maximum static) pressure of the fan, and multiple points in between, allowing us to compose the actual P-Q performance chart of any fan. The RPM reading is taken with the fan unobstructed (maximum flow), as the fan speed varies depending on the airflow impedance in conjunction with the design of the fan’s blades.

For noise measurements, we are using an Extech HD600 high sensitivity SPL meter. The noise of the fan is measured from 15 centimeters away, not one meter as IEC certifications require, as that would be far too great a distance to measure differences between nearly silent products. Note however that we are measuring the noise level of a fan with its flow unobstructed and the fan, to the best possible degree, uncoupled from the environment. The addition of fan grills, the installation on a cooler, and any other form of obstruction will increase the generated noise, as both aerodynamic and vibration noise will be added into the environment.

Test Results & Conclusion

The Sunon MFC0251V2-1Q02U-S99 is a robust performer across the entirety of the performance chart. At its maximum speed of 1900 RPM, it offers an airflow of 58.9 CFM and a static pressure of 2.48 mmH₂O. However, that performance comes with a noise output of 41.3 dB(A), which is quite noticeable and, in most cases, not really ahead of its competition. When compared to the Corsair ML120, another fan with a magnetic levitation engine, the Sunon model tends to offer significantly better performance by running about 300 RPM faster while generating about the same level of noise.

Overall, Sunon's 120mm MagLev fan stands out as a high-quality part, and better still it's priced competitively at around $11, offering substantial value for those looking for robust cooling solutions within budget constraints. When it's used correctly, the fan easily competes with, and generally outperforms, the best 120 mm products currently available – albeit not immensely so.

However "used correctly" is the operative term, as the MagLev engine makes the fan particular about its orientation. In short, these fans are not meant to be installed with the engine facing upwards, as this can jeopardize the integrity of the Vapo mechanism. As a result, Sunon's MagLev fan is really only good for horizontal uses – front and back air intake/exhaust – and shouldn't be used for vertical configurations at the top and bottom of computer cases.

Despite that, the 120mm MagLev fan does excel when it's in its niche, especially at its price. The biggest hurdle, in that case, is just acquiring a fan, as Sunon is primarily geared up to target the bulk OEM market and doesn't sell their fans in individual retail units. So prospective buyers will need to skip the Neweggs and Amazons of the world, and look instead at electronic and industrial suppliers like Digikey and Mouser.

As modern high-performance CPUs generate more heat, there's been a noticeable increase in the demand for powerful air coolers capable of managing these thermal challenges. Traditional stock air coolers, while sufficient for regular use, are typically designed to be cheap and relatively compact, leaving further improvements to noise control and peak cooling efficiency on the table. This gap has long prompted advanced users and system builders to opt for high-quality aftermarket coolers that designed to better handle the heat output from top-tier processors.

Just over 18 months ago, Intel launched their significantly revised ATX v3.0 power supply standard, and with it, the 600 Watt-capable 12VHPWR cable to power video cards and other high-drain add-in cards. The release of the standard came with a lot of fanfare and excitement – the industry was preparing for a future where even flagship video cards could go back to being powered by a single cable – but shortly after, things became exciting again for all the wrong reasons.

The new 12VHPWR connector proved to be less forgiving of poor connections between cables and devices than envisioned. With hundreds of watts flowing through the relatively small pins – and critically, insufficient means to detect a poor connection – a bad connection could result in a thermal runaway scenario, i.e. a melted connector. And while the issue was an edge case overall, affecting a fraction of a fraction of systems, even a fraction is too much when you're starting from millions of PCs, never mind the unhappy customers with broken video cards.

So the PC industry is taking a mulligan on the matter, quickly revising the ATX specification and the 12VHPWR connector to fix their design flaws. In its place we have the new ATX v.3.1 power supply specification, as well as the associated 12V-2×6 connector, the combination of which are intended to serve the same goals, but with far less of a chance of errant electricity causing damage.

Ultimately, the combination of the two new standards has required backwards-compatible changes on both the device (video card) side, as well as the power supply side. And as a result, power supply manufacturers are now in the process of releasing ATX v3.1-compliant PSUs that implement these revisions. For PSU vendors, the changes are relatively trivial overall, but they are none the less important changes that for multiple reasons, they are making sure to promote.

Getting down to business, the first ATX v3.1 power supply to enter our testing labs comes from ADATA sub-brand XPG, a prolific player in the PSU market. XPG recently expanded its product lineup with the introduction of the Core Reactor II VE series, the company's first foray into ATX 3.1-compliant PSUs. As a direct successor of the Core Reactor II series, the Core Reactor II VE is a relatively simple 80Plus Gold unit that distinguishes itself with its straightforward design, aimed at providing steady performance without the high expense.

In today’s review, we are taking a look at the 850W version of the Core Reactor II VE series, which is, for the time being, the most powerful ATX 3.1 unit XPG offers.

While the all-in-one CPU cooler industry is dominated, at least in mindshare, by flagship coolers from the industry’s biggest brands, the market segment overall has grown over the years to cover a much larger gamut of users. From flagship coolers to sub-$100 specials, effective AIO coolers have become available and affordable for most mid-range and higher builds. Thanks in part to some intensive competition in this space, we’ve seen several vendors bring down even 360mm coolers to the sub-$100 market in an effort to get in an edge over their competitors, and a sale in the process.

Looking at an opportunity to grow their own customer base, even the normally premium-focused AlphaCool has opted to get into this action with their Core Ocean lineup of coolers. And today, we're taking a closer look at the Core Ocean T38 360mm, AlphaCool's latest entry-level AIO cooler.

At a high level, the Core Ocean T38 has been designed to balance performance with manufacturing costs, allowing the company to put together an effective cooler that can still be priced low enough to reach budget-conscious consumers. Sticking with an aluminum radiator and keeping the frills such as RGB lighting to a minimum, the T38 is primarily aimed at system builders who require straightforward, effective cooling solutions – and without the complexity of AlphaCool's renowned open-loop custom liquid cooling kits. As we'll see, nothing comes for free, but AlphaCool has been able to put together a rather effective CPU cooler for $100 that's hard to ignore.

While desktop PC power supplies receive the bulk of enthusiasts’ attention for good reasons – not the least of which being the vast selection of options that comes from being a standardized part – power supplies as a whole aren’t just a concern for big PCs. With the majority of PC sales having flipped to notebook sales some years ago, notebook power supplies already lead the market in volume. And while most laptops don’t need the kind of massively powered PSUs that dominate the desktop space, even that is slowly changing as desktop replacement-class laptops increasingly grow in performance and power consumption.

Perhaps the poster-child for the high-performance, high-powered laptop is Eurocom, who has a long history of developing heavy-duty DTR laptops that are all but portable desktop systems. Following recent trends in GPU power consumption and in GPU popularity for both gaming and AI workloads, the company has been selling a range of “mobile supercomputers”, which are practically large, tailor-made laptops that rival even the best of desktop computers – and have the power requirements to match.

In order to power their own high-end laptops, Eurocom has developed a rather unusual 780W AC adapter for high-performance laptops. Intended to power the most powerful of powerful laptops, their latest power adapter can supply over three-quarters of a kilowatt of DC power; a desktop-like wattage for a desktop-like device. It’s a laptop power adapter that’s unique in its scale, and with some room to scale up even further.

Eurocom has offered this adapter for a few years now. But it’s taken on a new life as more laptops have been released that use such a large adapter (or two smaller 300W-ish power adapters). And, critically, Eurocom has made additional DC cable/connector sets for other manufactuers’ laptops, significantly increasing the number of systems it’s compatible with. Currently, Eurocom offers DC cables for the following laptops:

• Alienware M17x M18x; 1x DC Cable ; w/ barrel AW connector; 193cm/6.4ft 
• Alienware AREA 51m; 1x DC Cable + Splitter Box w/ 2x barrel AW connectors; 152cm/5ft 
• ASUS ROG G18 Strix; GX501V; GM501; GM501GM; GX531GM; 1x DC Cable; w/ barrel ROG connector 
• ASUS G703GX, GZ700GX; 1x DC Cable w/ 2x ROG barrel connectors; 152cm/5ft 
• CLEVO, OriginPC, Sager, XMG, EUROCOM laptops; 1x DC Cable; w/ 4-pin round connector; 182cm / 6ft 
• CLEVO X370SNx; 1x DC Cable; w/ square connector; 120cm / 3.8ft 
• CLEVO X170SM/X170KM; 1x DC Cable; w/ dual square connectors; 152cm / 5ft 
• Dell Precision 7720/7710; 1x DC Cable; w/ barrel Dell connector; 120cm / 3.8ft 
• MSI GE76, GT76, GT77, GE78HX Raider, Titan 18HX 1x DC Cable; w/ single square connector; 120cm / 3.8ft 
• MSI laptops & MSI Trident AS Gaming Desktops; 1x DC Cable; w/ 4-pin round connector; 182cm / 6ft 

The Eurocom 780W AC Adapter

Externally, the Eurocom 780W AC adapter looks like a hybrid between a PC PSU and a laptop adapter. It is shaped like an oversized laptop AC adapter but has a metallic body and cooling vents/fans. Eurocom advertises that it weighs “only 1.34kg”, which is the weight of an entire 14-inch laptop by comparison, but is relatively lightweight for a PSU with that kind of power output. The company logo is debossed across the top side of the adapter, with four round anti-slip pads found at its bottom. Care needs to be taken while moving it around because the metallic edges and weight can spell trouble for wooden surfaces.

Eurocom installed a small information display on the AC adapter, which shows the current, voltage, and power output, as well as the temperature of the adapter. It is not perfectly accurate – we can see it was reading a 12W load without a DC cable attached to the adapter – but it works as a basic reference. Next to it, there is a heavy-duty metallic connector for the DC cable. On the other side we can find a typical three-prong C14 AC cable receptacle, as well as an on/off switch, which is not something commonly found on laptop AC adapters.

Opening up the chassis, we can see that the Eurocom 780W AC adapter is not unlike common PC PSUs – just less complex due to the need to only generate a single 20V rail. The basic layout is identical, with an AC filter at the input consisting of four Y capacitors, two X capacitors, and two substantial filtering inductors, that leads to a rectifying bridge. The GBJ1508 bridge is made by HY Electronic Cayman Ltd, a Taiwanese company we're encountering for the first time.

Then we have an APFC circuitry with a massive Aishi 450V/560μF capacitor and a large filtering coil being its passive components, with a Toshiba K31N60W regulator on the same heatsink as the two MOSFETs that form a typical half-bridge configuration. Following that we have a small transformer and two Infineon 045N10N MOSFETs to generate the 20V power output. Cooling is provided by two Protechnic Electric MGT3812XB-W20 38 mm fans, which are small but high quality products with a double-ball bearing engine.

Test Results (~25°C Ambient)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, and various other bits and parts. 

The average efficiency of the Eurocom 780W AC adapter is very high, at 91.6% when the PSU is powered from an 230V AC source and drops down to 90.9% when powered from an 115V AC source. There is no 80Plus or similar efficiency certification covering this PSU, but there is legislation such as the Ecodesign 2019/1782 directive, and, even though the manufacturer does not fully publish its performance specs as the directive requires, the Eurocom 780W adapter seems to easily meet them. We must mention that this kind of PSU has an advantage over classic PC PSUs because it only generates a single voltage line, and conversion losses are lower, so it should not be directly compared to any multi-voltage output PSU.

The two small fans of the Eurocom 780W AC adapter seem hardwired to the power output of the unit, largely ignoring the temperature of the adapter and adjusting their speed only according to the load. Up to 40% load, which should cover the power needs of most gaming laptops anyway, the adapter is practically entirely silent. The speed of the fan gradually increases when the load is greater than 330 Watts, reaching terrifying noise figures at maximum load. Given the nature of the adapter, it is highly unlikely that it will operate at such high a load for prolonged periods of time, as even the laptops that require 2x330 Watt adapters will not continuously sustain such a high load.

Power Supply Quality 

The electrical performance of the Eurocom 780W AC adapter is surprisingly good compared to its datasheet specifications. Eurocom claims a maximum voltage ripple of 200 mV but we recorded a maximum of 116 mV, which is alright for a 20 V rail and better than we expected due to the mediocre secondary side filtering. Voltage regulation is very good, at just 1.2% across the nominal load range.

During our routine evaluation, we examine the fundamental protection features of all power supply units we review, including Over Current Protection (OCP), Over Voltage Protection (OVP), Over Power Protection (OPP), and Short Circuit Protection (SCP). The Eurocom 780W AC adapter behaves quite oddly here, as it has a rated output of 39 A and a maximum output of 45 A for 25 ms. However, we were able to draw 50 A from the unit, which is nearly 1000 Watts, for several minutes without triggering the OCP/OPP protection. The PSU did not show any serious signs of stress or overheating over that time, nor poor electrical performance. The OPP protection triggers immediately once the load is greater than 50.3 A – and also immediately resets and restarts the PSU when the load drops below 50.2A. It would seem that this platform was initially designed to be significantly more powerful and the OEM “forgot” to adjust the OCP/OPP trigger points.

Conclusion

The Eurocom 780W AC adapter melds raw power with innovation, presenting a piece that's as formidable as it is intriguing. With its substantial weight and metallic edges, it demands respect and caution, especially on delicate surfaces. However, its weight is justified by the impressive power output it delivers, making it a powerhouse that somewhat overshadows its bulky, heavy-set design. The inclusion of a display for monitoring performance is a smart touch, though its accuracy leaves room for improvement.

On the inside, Eurocom doesn't skimp on quality. The adapter's internals are a testament to careful selection and engineering, closely mirroring the complexity and efficiency of high-end PC PSUs. Its cooling system, though compact, functions well and provides good performance without compromising on noise levels — at least under most loads. That said, the adapter's noise profile at maximum load might not be everyone's cup of tea, hinting at a balance yet to be perfected between power and tranquility.

Overall, Eurocom's 780W AC adapter boasts commendable efficiency and electrical performance. But as a premium-priced product – a complete unit and cable will set you back at least $429 – it could benefit from a touch more finesse, particularly in terms of user safety and operational noise at high loads. Otherwise, I'm personally a bit surprised that Eurocom isn't offering a open-ended cable for DIY enthusiasts, which could broaden its appeal and utility. Such an addition would not only cater to a wider audience but also underscore Eurocom's commitment to versatility and innovation.

In sum, while the adapter stands out for its power and performance, there's also a clear avenue for Eurocom to enhance its appeal through minor, yet impactful, improvements.

With its substantial weight and metallic edges, it demands respect and caution, especially on delicate surfaces. However, its weight is justified by the impressive power output it delivers, making it a powerhouse that somewhat overshadows its bulky, heavy-set design. The inclusion of a display for monitoring performance is a smart touch, though its accuracy leaves room for improvement.

On the inside, Eurocom doesn't skimp on quality. The adapter's internals are a testament to careful selection and engineering, closely mirroring the complexity and efficiency of high-end PC PSUs. Its cooling system, though compact, functions well and provides good performance without compromising on noise levels — at least under most loads. That said, the adapter's noise profile at maximum load might not be everyone's cup of tea, hinting at a balance yet to be perfected between power and tranquility.

Overall, Eurocom's 780W AC adapter boasts commendable efficiency and electrical performance. But as a premium-priced product – a complete unit and cable will set you back at least $429 – it could benefit from a touch more finesse, particularly in terms of user safety and operational noise at high loads. Otherwise, I'm personally a bit surprised that Eurocom isn't offering a open-ended cable for DIY enthusiasts, which could broaden its appeal and utility. Such an addition would not only cater to a wider audience but also underscore Eurocom's commitment to versatility and innovation.

In sum, while the adapter stands out for its power and performance, there's also a clear avenue for Eurocom to enhance its appeal through minor, yet impactful, improvements.

Just over 18 months ago, Intel launched their significantly revised ATX v3.0 power supply standard, and with it, the 600 Watt-capable 12VHPWR cable to power video cards and other high-drain add-in cards. The release of the standard came with a lot of fanfare and excitement – the industry was preparing for a future where even flagship video cards could go back to being powered by a single cable – but shortly after, things became exciting again for all the wrong reasons.

The new 12VHPWR connector proved to be less forgiving of poor connections between cables and devices than envisioned. With hundreds of watts flowing through the relatively small pins – and critically, insufficient means to detect a poor connection – a bad connection could result in a thermal runaway scenario, i.e. a melted connector. And while the issue was an edge case overall, affecting a fraction of a fraction of systems, even a fraction is too much when you're starting from millions of PCs, never mind the unhappy customers with broken video cards.

So the PC industry is taking a mulligan on the matter, quickly revising the ATX specification and the 12VHPWR connector to fix their design flaws. In its place we have the new ATX v.3.1 power supply specification, as well as the associated 12V-2×6 connector, the combination of which are intended to serve the same goals, but with far less of a chance of errant electricity causing damage.

Ultimately, the combination of the two new standards has required backwards-compatible changes on both the device (video card) side, as well as the power supply side. And as a result, power supply manufacturers are now in the process of releasing ATX v3.1-compliant PSUs that implement these revisions. For PSU vendors, the changes are relatively trivial overall, but they are none the less important changes that for multiple reasons, they are making sure to promote.

Getting down to business, the first ATX v3.1 power supply to enter our testing labs comes from ADATA sub-brand XPG, a prolific player in the PSU market. XPG recently expanded its product lineup with the introduction of the Core Reactor II VE series, the company's first foray into ATX 3.1-compliant PSUs. As a direct successor of the Core Reactor II series, the Core Reactor II VE is a relatively simple 80Plus Gold unit that distinguishes itself with its straightforward design, aimed at providing steady performance without the high expense.

In today’s review, we are taking a look at the 850W version of the Core Reactor II VE series, which is, for the time being, the most powerful ATX 3.1 unit XPG offers.

While the all-in-one CPU cooler industry is dominated, at least in mindshare, by flagship coolers from the industry’s biggest brands, the market segment overall has grown over the years to cover a much larger gamut of users. From flagship coolers to sub-$100 specials, effective AIO coolers have become available and affordable for most mid-range and higher builds. Thanks in part to some intensive competition in this space, we’ve seen several vendors bring down even 360mm coolers to the sub-$100 market in an effort to get in an edge over their competitors, and a sale in the process.

Looking at an opportunity to grow their own customer base, even the normally premium-focused AlphaCool has opted to get into this action with their Core Ocean lineup of coolers. And today, we're taking a closer look at the Core Ocean T38 360mm, AlphaCool's latest entry-level AIO cooler.

At a high level, the Core Ocean T38 has been designed to balance performance with manufacturing costs, allowing the company to put together an effective cooler that can still be priced low enough to reach budget-conscious consumers. Sticking with an aluminum radiator and keeping the frills such as RGB lighting to a minimum, the T38 is primarily aimed at system builders who require straightforward, effective cooling solutions – and without the complexity of AlphaCool's renowned open-loop custom liquid cooling kits. As we'll see, nothing comes for free, but AlphaCool has been able to put together a rather effective CPU cooler for $100 that's hard to ignore.

While desktop PC power supplies receive the bulk of enthusiasts’ attention for good reasons – not the least of which being the vast selection of options that comes from being a standardized part – power supplies as a whole aren’t just a concern for big PCs. With the majority of PC sales having flipped to notebook sales some years ago, notebook power supplies already lead the market in volume. And while most laptops don’t need the kind of massively powered PSUs that dominate the desktop space, even that is slowly changing as desktop replacement-class laptops increasingly grow in performance and power consumption.

Perhaps the poster-child for the high-performance, high-powered laptop is Eurocom, who has a long history of developing heavy-duty DTR laptops that are all but portable desktop systems. Following recent trends in GPU power consumption and in GPU popularity for both gaming and AI workloads, the company has been selling a range of “mobile supercomputers”, which are practically large, tailor-made laptops that rival even the best of desktop computers – and have the power requirements to match.

In order to power their own high-end laptops, Eurocom has developed a rather unusual 780W AC adapter for high-performance laptops. Intended to power the most powerful of powerful laptops, their latest power adapter can supply over three-quarters of a kilowatt of DC power; a desktop-like wattage for a desktop-like device. It’s a laptop power adapter that’s unique in its scale, and with some room to scale up even further.

Eurocom has offered this adapter for a few years now. But it’s taken on a new life as more laptops have been released that use such a large adapter (or two smaller 300W-ish power adapters). And, critically, Eurocom has made additional DC cable/connector sets for other manufactuers’ laptops, significantly increasing the number of systems it’s compatible with. Currently, Eurocom offers DC cables for the following laptops:

• Alienware M17x M18x; 1x DC Cable ; w/ barrel AW connector; 193cm/6.4ft 
• Alienware AREA 51m; 1x DC Cable + Splitter Box w/ 2x barrel AW connectors; 152cm/5ft 
• ASUS ROG G18 Strix; GX501V; GM501; GM501GM; GX531GM; 1x DC Cable; w/ barrel ROG connector 
• ASUS G703GX, GZ700GX; 1x DC Cable w/ 2x ROG barrel connectors; 152cm/5ft 
• CLEVO, OriginPC, Sager, XMG, EUROCOM laptops; 1x DC Cable; w/ 4-pin round connector; 182cm / 6ft 
• CLEVO X370SNx; 1x DC Cable; w/ square connector; 120cm / 3.8ft 
• CLEVO X170SM/X170KM; 1x DC Cable; w/ dual square connectors; 152cm / 5ft 
• Dell Precision 7720/7710; 1x DC Cable; w/ barrel Dell connector; 120cm / 3.8ft 
• MSI GE76, GT76, GT77, GE78HX Raider, Titan 18HX 1x DC Cable; w/ single square connector; 120cm / 3.8ft 
• MSI laptops & MSI Trident AS Gaming Desktops; 1x DC Cable; w/ 4-pin round connector; 182cm / 6ft 

The Eurocom 780W AC Adapter

Externally, the Eurocom 780W AC adapter looks like a hybrid between a PC PSU and a laptop adapter. It is shaped like an oversized laptop AC adapter but has a metallic body and cooling vents/fans. Eurocom advertises that it weighs “only 1.34kg”, which is the weight of an entire 14-inch laptop by comparison, but is relatively lightweight for a PSU with that kind of power output. The company logo is debossed across the top side of the adapter, with four round anti-slip pads found at its bottom. Care needs to be taken while moving it around because the metallic edges and weight can spell trouble for wooden surfaces.

Eurocom installed a small information display on the AC adapter, which shows the current, voltage, and power output, as well as the temperature of the adapter. It is not perfectly accurate – we can see it was reading a 12W load without a DC cable attached to the adapter – but it works as a basic reference. Next to it, there is a heavy-duty metallic connector for the DC cable. On the other side we can find a typical three-prong C14 AC cable receptacle, as well as an on/off switch, which is not something commonly found on laptop AC adapters.

Opening up the chassis, we can see that the Eurocom 780W AC adapter is not unlike common PC PSUs – just less complex due to the need to only generate a single 20V rail. The basic layout is identical, with an AC filter at the input consisting of four Y capacitors, two X capacitors, and two substantial filtering inductors, that leads to a rectifying bridge. The GBJ1508 bridge is made by HY Electronic Cayman Ltd, a Taiwanese company we're encountering for the first time.

Then we have an APFC circuitry with a massive Aishi 450V/560μF capacitor and a large filtering coil being its passive components, with a Toshiba K31N60W regulator on the same heatsink as the two MOSFETs that form a typical half-bridge configuration. Following that we have a small transformer and two Infineon 045N10N MOSFETs to generate the 20V power output. Cooling is provided by two Protechnic Electric MGT3812XB-W20 38 mm fans, which are small but high quality products with a double-ball bearing engine.

Test Results (~25°C Ambient)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, and various other bits and parts. 

The average efficiency of the Eurocom 780W AC adapter is very high, at 91.6% when the PSU is powered from an 230V AC source and drops down to 90.9% when powered from an 115V AC source. There is no 80Plus or similar efficiency certification covering this PSU, but there is legislation such as the Ecodesign 2019/1782 directive, and, even though the manufacturer does not fully publish its performance specs as the directive requires, the Eurocom 780W adapter seems to easily meet them. We must mention that this kind of PSU has an advantage over classic PC PSUs because it only generates a single voltage line, and conversion losses are lower, so it should not be directly compared to any multi-voltage output PSU.

The two small fans of the Eurocom 780W AC adapter seem hardwired to the power output of the unit, largely ignoring the temperature of the adapter and adjusting their speed only according to the load. Up to 40% load, which should cover the power needs of most gaming laptops anyway, the adapter is practically entirely silent. The speed of the fan gradually increases when the load is greater than 330 Watts, reaching terrifying noise figures at maximum load. Given the nature of the adapter, it is highly unlikely that it will operate at such high a load for prolonged periods of time, as even the laptops that require 2x330 Watt adapters will not continuously sustain such a high load.

Power Supply Quality 

The electrical performance of the Eurocom 780W AC adapter is surprisingly good compared to its datasheet specifications. Eurocom claims a maximum voltage ripple of 200 mV but we recorded a maximum of 116 mV, which is alright for a 20 V rail and better than we expected due to the mediocre secondary side filtering. Voltage regulation is very good, at just 1.2% across the nominal load range.

During our routine evaluation, we examine the fundamental protection features of all power supply units we review, including Over Current Protection (OCP), Over Voltage Protection (OVP), Over Power Protection (OPP), and Short Circuit Protection (SCP). The Eurocom 780W AC adapter behaves quite oddly here, as it has a rated output of 39 A and a maximum output of 45 A for 25 ms. However, we were able to draw 50 A from the unit, which is nearly 1000 Watts, for several minutes without triggering the OCP/OPP protection. The PSU did not show any serious signs of stress or overheating over that time, nor poor electrical performance. The OPP protection triggers immediately once the load is greater than 50.3 A – and also immediately resets and restarts the PSU when the load drops below 50.2A. It would seem that this platform was initially designed to be significantly more powerful and the OEM “forgot” to adjust the OCP/OPP trigger points.

Typical CPU coolers do the job for standard heat management but often fall short when it comes to quiet operation and peak cooling effectiveness. This gap pushes enthusiasts and PC builders towards specialized aftermarket solutions designed for their unique demands. The premium aftermarket cooling niche is fiercely competitive, with brands vying to offer top-notch thermal management solutions.

Today we're shining a light on DeepCool's AK620 Digital cooler, a notable entry in the high-end CPU cooler arena. At first blush, the AK620 Digital stands out from the crowd mostly for its integrated LCD screen. Yet aesthetics aside, underneath the snappy screen is a tower cooler that was first and foremost engineered to exceed the cooling needs of the most powerful mainstream CPUs. And it's a big cooler at that: with a weight of 1.5Kg and 162mm tall, this is no lightweight heatsink and fan assembly. All of which helps to set it apart in a competitive marketplace.

Cooler Master, renowned for its pioneering role in cooling technologies, has evolved into a key player in the PC components industry, extending its expertise to include cases and power supply units (PSUs). The company's current catalog is a testament to its commitment to diversity, featuring over 75 PC cases, 90 coolers, and 120 PSUs, all designed to cater to the evolving demands of tech enthusiasts and professionals alike.

This review focuses on the Cooler Master MWE Gold V2 750W PSU, a key offering in Cooler Master's power supply lineup that embodies the brand's vision of combining quality and value. The MWE Gold V2 series is engineered to offer solid performance and reliability at a price point that appeals to system builders and gamers looking for an entry-level to mid-range solution. As a result, the MWE Gold V2 750W has been a consistently popular offering within Cooler Master's catalog, often cycling in and out of stock depending on what sales are going on. This makes the PSU a bit harder to track down in North America than it does Europe, and quick to vanish when it does show up.

Alphacool, a renowned name in the realm of PC cooling solutions, recently launched their Apex Stealth Metal series of cooling fans. Prior to their launch, the new fans had amassed a significant amount of hype in the PC community, in part because of the unfortunate misconception that the entire fan would be made out of metal.

Regardless of whether they're made entirely out of metal or not, however, these fans are notable for their unique construction, combining a metallic frame with plastic parts that are decoupled from the metal. This design choice not only contributes to the fan's aesthetic appeal but also plays a role in its operational efficiency.

The series includes two distinct models, the Apex Stealth Metal 120 mm and the Apex Stealth Metal Power 120 mm, distinguished primarily by their maximum rotational speeds. The former reaches up to 2000 RPM, while the latter, designed for more demanding applications, can achieve a remarkable 3000 RPM. Available in four color options – White, Matte Black, Chrome, and Gold – these fans offer a blend of style and functionality, making them a versatile choice for various PC builds.

Cooler Master, renowned for its pioneering role in cooling technologies, has evolved into a key player in the PC components industry, extending its expertise to include cases and power supply units (PSUs).

For established PC peripheral vendors, the biggest challenge in participating in the highly commoditized market is setting themselves apart from their numerous competitors. As designs for coolers and other peripherals have converged over the years into a handful of basic, highly-optimized designs, developing novel hardware for what is essentially a "solved" physics problem becomes harder and harder. So often then, we see vendors focus on adding non-core features to their hardware, such as RGB lighting and other aesthetics. But every now and then, we see a vendor go a little farther off of the beaten path with the physical design of their coolers.

Underscoring this point – and the subject of today's review – is Enermax's latest all-in-one (AIO) CPU cooler, the LiqMaxFlo 360mm. Designed to compete in the top-tier segment of the cooling market, Enermax has opted to play with the physics of their 360mm cooler a bit by making it 38mm thick, about 40% thicker than the industry average of 27mm. And while Enermax is hardly the first vendor to release a thick AIO cooler, they are in much more limited company here due to the design and compatibility trade-offs that come with using a thicker cooler – trade-offs that most other vendors opt to avoid.

The net result is that the LiqMaxFlo 360mm gets to immediately start off as differentiated from so many of the other 360mm coolers on the market, employing a design that can give Enermax an edge in cooling performance, at least so long as the cooler fits in a system. Otherwise, not resting on just building a bigger cooler, Enermax has also equipped the LiqMaxFlo 360mm with customizable RGB lighting, allowing it to also cater to the aesthetic preferences of modern advanced PC builders. All together, there's a little something for everyone with the LiqMaxFlo 360mm – and a lot of radiator to cram into a case. So let's get started.

A recall on 12VHPWR angled adapters from CableMod has reached its next stage this week, with the publication of a warning document from the U.S. Consumer Product Safety Commission. Referencing the original recall for CableMods' V1.0 and V1.1 adapters, which kicked off back in December, the CPSC notice marks the first involvement of government regulators. And with that has come to light a bit more detail on just how big the recall is overall, along with an estimated failure rate for the adapters of a hair over 1%.

According to the CPSC notice, CableMod is recalling 25,300 adapters, which were sold between February, 2023, and December, 2023. Of those, at least 272 adapters failed, as per reports and repair claims made to CableMod. That puts the failure rate for the angled adapters at 1.07% – if not a bit higher due to the underreporting that can happen with self-reported statistics. All told, the manufacturer has received at least $74,500 in property damage claims in the United States, accounting for the failed adapters themselves, as well as the video card and anything else damaged in the process.

As part of the recall, CableMod has asked owners of its angled 12VHPWR adapters V1.0 and V1.1 to stop using them immediately, and to destroy them to prevent future use. Buyers can opt for a full refund of $40, or a $60 store credit.

It is noteworthy that, despite the teething issues with the initial design of the 12VHPWR connector – culminating with the PCI-SIG replacing it with the upgraded 12V-2x6 standard – the issue with the CableMod adapters is seemingly distinct from those larger design flaws. Specifically, CableMod's recall cites issues with the male portion of their adapters, which was not altered in the 12V-2x6 update. Compared to 12VHPWR, 12V-2x6 only alters female plugs (such as those found on video cards themselves), calling for shorter sensing pins and longer conductor terminals. Male plugs, on the other hand, remain unchanged, which is why existing PSU cables made for the 12VHPWR remain compatible (and normally safe) with 12V-2x6 video cards. Though as cable mating is a two-way dance, it's unlikely having to plug into inadequate 12VHPWR female connectors did CableMod any favors here.

Today we're looking at a all-in-one closed loop cooler from a face that's new to AnandTech: Geometric Future. Founded in 2020, Geometric Future is a PC components manufacturer with a goal of setting themselves apart in the crowded PC marketplace by redefining modern aesthetics. Their approach to design emphasizes the application of geometric elements and minimalist philosophy, as reflected in their slogan, "Simplify". They regard themselves as a potential future backbone in China's design industry, starting with a small step in the IT sector.

For such a new company, Geometric Future has already made significant strides in the realm of PC power and cooling products. One of their most notable products – and what we're reviewing today – is the Eskimo Junior 36, an all-in-one CPU liquid cooler available in 240mm and 360mm sizes. This cooler is designed with a minimalist aesthetic in mind, featuring a simplistic CPU block and equipped with high-performance Squama 2503 fans. Geometric Future pitches the Eskimo Junior 36 as being engineered to provide an optimal balance of cooling efficiency and aesthetics, making it able to achieve excellent cooling capabilities while maintaining low noise levels.

But marketing claims aside, we shall see where it stands in today’s highly competitive market in this review.
