Analysis: RGB LED implementation changes fan noise

The headline may sound strange, but after reading the article it will make sense. After modifying a fan from unlit to lit, its noise level can change for a very simple reason. This is true even if the shape of the rotor or the operating speed has been maintained. As far as noise is concerned, a change by integrating ARGB LEDs does not always lead to a worse result. Still, it is important to know why any differences occur in the first place. Read more “Analysis: RGB LED implementation changes fan noise” »

Endorfy Fluctus 140 PWM ARGB works, looks come second

The first Fluctus 120 PWM fans marked a great qualitative progress in SilentiumPC production (now Endorfy). Nevertheless, they had their flaws, which the developers are gradually eliminating and, based on the measurement results, the newer 140 mm Fluctus can be said to be a clear improvement. The Fluctus 140 PWM ARGB stands out nicely from other fans in its price category. Read more “Endorfy Fluctus 140 PWM ARGB works, looks come second” »

Top price/performance in 15 mm – Arctic P12 Slim PWM PST

Low-profile fans are often seen as compromise solutions that will not achieve the efficiency of thicker models. This may or may not be true. In practice, the Arctic P12 Slim beats a number of full-size fans. Sure, Arctic’s 15mm fan has many shortcomings, but these are vindicated by the very low price. In the 120mm format, it is one of the cheapest, but definitely not the “weakest” slim fans. Read more “Top price/performance in 15 mm – Arctic P12 Slim PWM PST” »

BeQuiet! Silent Wings Pro 4 (BL099): A 140mm sovereign

Finally, a 140mm fan that doesn’t wade between the 120mm ones, but has a clear edge over them – even the “best” ones. And it’s a completely different story than its smaller brother, whose biggest negatives are avoided by the 140mm model. But there is one new, rather unnecessary flaw. However, it can be eliminated, with a trade-off. But you might not even notice it, and then you can consider this fan an excellent choice. Read more “BeQuiet! Silent Wings Pro 4 (BL099): A 140mm sovereign” »

BeQuiet! Light Wings fans now also in white

For users who prefer a contrast to the traditional stuff, BeQuiet! has released white Light Wings fans, in both 120mm and 140mm formats. By the standards of lighted fans, these will be models with some of the stiffest blades, especially in the smaller format. Because of its design characteristics, it is highly likely to achieve extremely low vibration alongside a superbly non-intrusive sound profile. Read more “BeQuiet! Light Wings fans now also in white” »

Prisma AL-14 PWM: The best 140mm fan by Fractal Design?

Fractal Design claims the Prisma models as its most efficient 140mm fans. According to the specs, they are supposed to achieve the highest airflow at a lower noise level than the Aspect 14s. However, this is physically impossible due to the constructional differences of the two fans. The title of the article has a bit of a pejorative tone and while the Prisma AL-14 PWM is a decent fan, it already has a superior from its own ranks.

Gigabyte Aorus 140 ARGB: Short/quiet and lighted (blades)

Blade length is always the “topic”, but will be more common with 140mm fans than smaller variants. Some bet on long blades for preference of selected features, the other manufacturer on short ones. And such (short) and overall more robust blades are also used by the 140mm Aorus fan. From certain points of view this is quite a big advantage, but for which something had to be sacrificed. It’s a quid pro quo. Read more “Gigabyte Aorus 140 ARGB: Short/quiet and lighted (blades)” »

BeQuiet! Light Wings (140 mm): Different size, different geometry

We analyzed the “Light Wings” fan fairly recently, but that was in the 120 mm format. BeQuiet! approached the 140mm model a little differently. Although the frame is only proportionally enlarged, the shape of the rotor is already significantly different. It relies on long, curved blades, which look great in this cross-section, but there are some design caveats. Still, in some applications, this fan excels. Read more “BeQuiet! Light Wings (140 mm): Different size, different geometry” »

FD Aspect 14 RGB PWM: Larger rotor, higher airflow per dBA

Starting with the Fractal Design Aspect 14 RGB PWM test, we are starting to build a database of 140mm fan results. These may have a smaller market presence due to poorer compatibility, but compared to the 120mm models they have the makings of higher efficiency, which is why they are more popular among many users. The Aspect 14 RGB PWM fan, in addition to its aerodynamic qualities, also fights for customer favour with its lighting. Read more “FD Aspect 14 RGB PWM: Larger rotor, higher airflow per dBA” »

DeepCool FK120 fan: Efficiency ceiling for some scenarios

It is made in the same injection mould as the FC120, but still has noticeably better properties. Stronger material, higher weight, different bearings and a more powerful motor make the FK120 one of the most attractive options among inexpensive fans. But that’s only assuming the “right” adjustment. Outside of that, this fan can be quite uncomfortable and ironically for the same reason it is sometimes unbeatable.

Asus TUF Gaming TF120: Cheap, lighted and efficient fan

Asus’s efforts in the field of standalone PC fans are on the rise. After the premiere in the form of the ROG XF120, there is now the half-price TUF TF120, which also gives more attractive results in some applications. And that’s even compared to other, similar fans with ARGB LEDs. The geometry of the TF120 is quite sensible, which is why it often beats its competitors in its price range.

Gamers Nexus fan testing won’t come, was it all talk

Wake up, Steve! You kind of slept through a convenient opportunity to divulge what’s going on with the fan testing that your audience funded a long time ago. Never mind, I’ll blog a bit and shed some light on it myself. I understand that you’ve reached a difficult, stalemate situation that’s hard to come out with to the public and it’s more effective to sweep inconvenient things under the rug (again). That too is the style of Gamers Nexus, history repeats itself. Read more “Gamers Nexus fan testing won’t come, was it all talk” »

Year of the fan is here: by 2023, there will be 70 of them compared

Last year’s tally of fans tested ends at 34 models. We don’t know what number it will stop at one day over the years, but our plan for the next twelve months is clear: Push hard on fan topics. Not only by adding to the record number of fans, but also by popular education on the physics that is essential to a proper understanding of exactly how fans work. The goal is for you to have a clarity about everything. Read more “Year of the fan is here: by 2023, there will be 70 of them compared” »

BeQuiet! Light Wings (BL072): Sturdy rotor with ARGB LEDs

Illuminated fans from BeQuiet! have the advantage over many competing models in a more robust rotor design. This is also due to the fact that it is not made of “light conductive” material and therefore some may not like the Light Wings fans, but aerodynamically they have the edge over other models. This is not only because of the choice of raw materials and their robustness, but also the overall shape of the blades. Read more “BeQuiet! Light Wings (BL072): Sturdy rotor with ARGB LEDs” »

Removing notches on fan blades? Sometimes a mistake

On edges of blades of some fans there are small notches forming a kind of teeth, typically on the trailing edges, closer to the motor. These elements serve to break up tonal peaks, and it’s curious that manufacturers are abandoning them rather than adding them. In some designs, however, such a modification can be seen as a backwards move; elsewhere it’s an understandable one. We have a few examples for you. Read more “Removing notches on fan blades?
