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” »

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.

Noctua plans changes: surprise fan grilles, delays of key products

Along with a cooler release, Noctua has updated their roadmap, leaving no stone unturned. A lot of products are being pushed to a later date, including the upcoming 140 mm fans. But the good news is that at least fan grilles, which will surely appear in our tests sooner or later, have appeared out of the blue in the window for the coming months or maybe just weeks.

“Bigger, better”, SilverStone releases 160 mm sharkskin fan

As you know, the airflow of fans depends on the area of their blades. The larger the area, the better the fan is able to achieve higher efficiency. However, you can’t push it indefinitely, and maximum dimensions are limited by both heatsinks and PC cases. However, SilverStone has now come up with a fan that has the same hole spacing as the standard 140mm models, only with a larger cross-section compared to them.

Cooler Master SickleFlow 120 ARGB: If not for the horrible rattling…

It could have been a very good, affordable fan with lighting. Moreover, the SickleFlow 120 ARB rotor design is efficient, at an excellent level, but all the good features are killed by one thing – an extremely noisy motor. It’s so noisy that a return trip from the factory output control would be appropriate. And it’s not just your everyday whir that you hear only from centimeters away. No one will ever miss this sound.

Alphacool SL-15 PWM: Low profile does not equal low airflow

There are situations where standard 25 mm fans will not fit. Even the 120 mm format therefore offers lower alternatives. The first thing that naturally comes to mind is that such fans mean a trade-off in cooling efficiency. However, this may not be true and the hassle of thinking about how to fit a thicker fan inside may even be quite unnecessary. A well-designed rotor can achieve fully-fledged results when compared to a thicker rotor, even if it is slimmer. Read more “Alphacool SL-15 PWM: Low profile does not equal low airflow” »

Arctic BioniX F120: The efficient fan that loses to obstacles

We watched the Arctic BioniX F120’s behaviour during tests with our jaws dropped. First of all, because in some situations it really has top efficiency, and at a low price of around ten euros. But that’s how it excels in theoretical applications where nothing stands in it’s way. When it works with a filter, grille or radiator, the magic of the BioniX is gone. Such a significant turnaround is unique and fascinating. Read more “Arctic BioniX F120: The efficient fan that loses to obstacles” »

We cut the grille out of the Air Penetrator. Better than the original?

Every SilverStone Air Penetrator series fan includes an aerodynamic grille on the exhaust. This is firmly attached to the frame, but can be forcibly removed. The AP123 fan has gone through such a process and we will demonstrate the benefits of this grille. Whether it is good or bad cannot be noted briefly, but the way SilverStone communicates it to the public is again a bit unfortunate and misleading.

Akasa metal filter beat the “plastics” in tests by a good chunk

We have tested a dust filter that combines the best features of plastic and nylon filters. It has high mechanical resistance, is easy to clean and yet also has low restrictiveness, so it does not significantly change the sound of the fan and does not increase its noise level. Compared to plastic filters, it does not even “hiss”. This addition thus extends the database of results with the latest type of dust filter, one with a metal grille.

The AP123 or how SilverStone’s been fooling people for years

A harsh headline, but a fair one. We always try to find mostly good things when testing, but sometimes it’s tricky. That’s the case here, where SilverStone is misleading its customers. The grille doesn’t significantly increase noise? We have no sympathy for hoaxes like this. Especially when it’s all “well thought out” and staged. Such practices do not shed a good light on the combination of three different blade shapes, which actually has something to it.

Vibration: a parameter to which fan companies turn a blind eye

In addition to basic parameters such as air flow, static pressure and noise level, information on vibration intensity should also be provided with fans. But it’s not. Manufacturers do not seem to be too concerned about this issue and are very lax in their approach. This is a pity, because the noise levels quoted are very abstract quantities, which in practice are shaped by the amount of fan vibration.

SilentiumPC Fluctus 120 PWM: “Miracle” fan from the Fera 5

SilentiumPC presents the Fluctus 120 PWM as its very best fan. But, to beat the whirring Sigma Pro 120 PWM and the obviously sketchy Sigma Pro Corona RGB 120 is relatively simple. The company’s marketing, however, talks about psychoacoustic optimizations. And while there’s no reason to smirk (psychoacoustics is a legitimate scientific field), there were some imperfections that the Poles didn’t avoid.

PWM vs. DC control. Why do fans work better with impulses?

We avoid it like the plague when it comes to backlighting LCD monitors, but we can’t imagine the best fans without it. We’re talking about pulse-width modulation for voltage regulation. In this article, we will explain in the simplest possible terms the reason why PWM regulation is gradually replacing linear regulation. Related to this in computers is the strong disproportion of 3-pin to 4-pin fans, of which there are considerably more. Read more “PWM vs. DC control. Why do fans work better with impulses?” »

Akasa releases suspended fans resistant to dust and water

Added value in fans can take different forms. In the case of Akasa’s new OTTO SF12 and OTTO SC12 fans, it is dust resistance and the fans are also not to be disrupted by contact with liquid. Such designs are typically suited to the harsh ambient conditions of industrial plants. But neither airflow nor pressure is supposed to be on the second track. Finally, the fans also excel with a sophisticated anti-vibration system. Read more “Akasa releases suspended fans resistant to dust and water” »

MSI MEG Silent Gale P12: A dominant all-rounder for a price

While the Silent Gale P12 isn’t the first fan in MSI’s lineup (like the Strix XF120 from Asus), it beats anything previous from the company by a mile. This is by the efficiency of the rotor, which is suitable for radiators as well as for a case, but also by the overall robust design. There’s a big, powerful but quiet motor, and you won’t even know about the hydrodynamic bearings. Read more “MSI MEG Silent Gale P12: A dominant all-rounder for a price” »
