Noctua NF-A12x25 PWM: The most fine-tuned fan of its kind

All the glory and respect of the Noctua NF-A12x25 “sterrox” fan is well deserved. We waited a long time to release its tests, mainly because it was necessary to analyze more seemingly similar designs first. This is necessary to understand why Noctua’s most popular fan among standard thickness models has no competition. We can responsibly say that even though we have only tested a fraction of all the fans. Read more “Noctua NF-A12x25 PWM: The most fine-tuned fan of its kind” »

Adata is not afraid, they gave the XPG Hurricane holey blades

These are truly unconventional fans. While the rotor shapes tend to vary across different models, in different materials, the XPG Hurricane design clearly stands out among the rest. They have sort of dual blades and prominent protrusions and, imagine, some sort of openings as well. Overall, the shape of the blades is more complex and it is not a typical quadrilateral geometry either. How can this possibly work?

Akasa Alucia SC12: Efficient shapes vs. soft material

Few fans can wow us at first glance the way the Alucia SC12 from Akasa has done. Its build looks quite compelling in this price range. However, on a second look after detailed testing comes some sobering. But even though the high (even exorbitantly high) expectations have not been met, in some aspects the Alucia SC12 beats attractive, similarly cheap competitors in some situations.

Static pressure vs. airflow, part 3/3: P/Q curves are misleading

And we come to the finale, in which we’ll look at the extremely popular line graphs that express the relationship between airflow and static pressure. These present, in a sophisticated and seemingly credible way, which fan will be more effective in which environment. As it happens, however, it is mainly a marketing tool rather than something useful that can really be relied upon. Read more “Static pressure vs. airflow, part 3/3: P/Q curves are misleading” »

Silent Wings Pro 4 (BL098) in-depth review: Hard BeQuiet! KO

All the secrets around the BeQuiet! Silent Wings (Pro) 4 are over and the detailed analyses of the sub-features begin. And it’s great that we can be a part of it. This is, after all, without a doubt, the biggest “cooling” event of the year, and it’s spicier than we thought. The new BeQuiet! fans may be the absolute top of the line, but they haven’t avoided certain imperfections that you have to take into account.

Thermalright X-Silent 120: Quiet operation for a bargain

Thermalright fans have been somewhat overshadowed by great heatsink throughout this company’s history. For a long time, even relatively high minimum speeds were awkward. These have now been tamed for most current models and the X-Silent 120 has a superbly low top speed as well. This is the “slowest” fan we have tested to date. With a price of under five euros, it also ranks among the cheapest you can buy. Read more “Thermalright X-Silent 120: Quiet operation for a bargain” »

Static pressure vs. airflow, part 2/3: Measuring performance on fins

No one, no one at all, can claim based on any tests that one fan is a touch more or less efficient than the other for radiators or cooler heatsinks in general. Technically it’s impossible, and not just because of the huge design diversity of fins. However, after in-depth analyses, one can work one’s way to comparisons that have a high predictive value with a certain amount of universality.

Sightly and efficient: the Fractal Design Aspect 12 RGB PWM test

An old-school rotor with one small aerodynamic tweak, the shortcomings of the Dynamic series of fans removed, and the addition of ARGB LED lighting. There are negatives too, but with the right application you can neatly avoid them. Overall, though, Fractal Design’s Aspects are functionally among the most feature-rich of what’s available in the current lineup of LED fans.

Gelid Zodiac fan: ARGB LED and excellent price/performance ratio

Aside from whether the fan is named after the zodiac or a serial killer from California, we know all about Gelid’s latest fan. In the end, the inspiration may stem from the latter as well. After all, it has a backlight option and at the same time “kills”, performance-wise, the price-equivalent fans without it. And attractive models at that. But there is one thing that can erase all the good features. Read more “Gelid Zodiac fan: ARGB LED and excellent price/performance ratio” »

Dynamic X2 GP-12 PWM: Fractal Design knows what works in cases

Sometimes they don’t even get a chance and are immediately replaced by other, “better” ones. We’re talking about fans that come pre-installed in computer cases. We are going to test one of them now and although there are reasons to replace the Dynamic X2 GP-12 (PWM), be careful not to end up being worse off. After all, these aren’t exactly ordinary fans. They even have more specific aerodynamics and acoustics modifying features. Read more “Dynamic X2 GP-12 PWM: Fractal Design knows what works in cases” »

BeQuiet! Pure Wings 2 (BL039): It wouldn’t do without the grooves

So, now we get to see what the grooves on the entire surface of the blades, which are typical of BeQuiet! fans, are worth! Judging by the geometry, we were initially concerned that the results might go in a similar direction to the Arctic BioniX F120. But it’s a lot better than that, and the 120 mm Pure Wings 2 even achieves a top price/performance ratio while running very quietly. The best of the fans tested so far. Read more “BeQuiet! Pure Wings 2 (BL039): It wouldn’t do without the grooves” »

Gigabyte Aorus 120 ARGB: Not just stylish, but a proper fan

Gigabyte’s new fan stands out from the crowd of flashy, inefficient PC components. The Aorus 120 ARGB may entice the user with its illuminated rotor, but the features that make a fan a fan don’t play second fiddle either. Although there is still room for tuning and improvement, the Aorus 120 ARGB excels in many ways and beats even competing models from traditional fan manufacturers in some areas of application.

Arctic BioniX P120 A-RGB: The lit specialist for filters and grilles

Now that’s what we call a turnaround. Remember how the BioniX F120 failed on obstacles? The newer BioniX P120 (A-RGB) no longer has such a fundamental limitation. On the contrary, it is significantly less stifled by obstacles than many competing fans. Just tame those vibrations, fine-tune the acoustics, where there are some flaws, and it’ll be great. The basis (the rotor) is better in practice than the label parameters suggest. Read more “Arctic BioniX P120 A-RGB: The lit specialist for filters and grilles” »

Akasa OTTO SF12: Anti-vibration membrane, wavy blades and IP68

Predisposed to more demanding industrial conditions, Akasa OTTO fans go well beyond “normal” home computer use. Complete water and dust resistance, three-phase torque and, above all, a unique vibration elimination system. The effectiveness of the proven “S-Flow” rotor is high, but there is one thing Akasa has overdone a bit. That is, if the OTTO SF12 fan is really meant for system cooling.

Among the new Akasa fans is also the dangerous Alucia SC

Although it didn’t look like it at first, Akasa will sell the fan from the Alucia H4 cooler separately. We had it briefly in our wind tunnel and it definitely has the potential to succeed in the mid-range segment. Then there are the illuminated Soho AR and Vegas A fans based on it, which are also sold in unconventional “Siamese twins or triplets” variants with a common frame for two or three rotors.
