Big test of 120 mm fans. We known everything about eight of them

Measuring the intensity (and power draw) of lighting

To write that we have something mapped out to the last detail is perhaps too bold, but after proper preparation, few pieces of hardware are as easy to evaluate as fans. Of course, this had to be preceded by long preparations, developing a methodology, but you already know the story. What you don’t know yet is the first fruit, or rather the results of Akasa, SilentiumPC, SilverStone, Xigmatek or more exotic Reeven fans.

Measuring the intensity (and power draw) of lighting

Modern fans often include lighting. This is no longer a “cooling” parameter, but for some users the presence of (A)RGB LEDs is important. Therefore, we also measure how intense this lighting is in our tests. These tests are the only ones that take place externally, outside the wind tunnel.
We record the luminosity of the fans in a chamber with reflective walls. This internal arrangement is important to increase the resolution for us to measure anything at all with lower luminosity fans. But also so that the readings do not blend together and it is obvious which fan is emitting more light and which one less.

Fan in the light chamber to measure the intensity of (A)RGB LEDs

The illumination intensity is measured in the horizontal position of the fan, above which is the lux meter sensor (UNI-T UT383S). This is centered on the illumination intensity sensing chamber.
The illumination is controlled via an IR controller and the hue is set to RGB level 255, 255, 255 (white). We record the brightness at maximum and minimum intensity. According to this, you can easily see if the brightness is high enough, but conversely also if the lower level is low enough for you.

In addition to the brightness intensity, we also measure the power draw that it requires. This is again through the shunt, which is between the Gophert CPS-3205 power supply and the (A)RGB LED driver. After this we get a reading of the lighting power draw. In the graphs we show it separately, but also in sum with the motor power draw as the total maximum fan power.

Retrotest: 8× PC case. From small to “large”

In the archives we found some remarkable tests that have never been published in English. Although they are heavily out of date ( cases included have not been sold for a long time), it illustrates well the possible impact of cooling across a wide variety of designs. And by those we also mean completely passive solutions that use their own shell to dissipate heat, as well as rather larger midi-towers and also something in between.

In vivo fan tests: 14 models in system positions

Here and there we come across the opinion that it is advisable to test fans in real life conditions, which we can easily refute. At the same time, we understand that a layman can best identify with the differences in component temperatures that arise precisely due to different fan airflows. To help you see the correlations of such tests with results from “unnatural” environments, here’s something we remembered. Read more “In vivo fan tests: 14 models in system positions” »

Akasa Gecko Pro: An SSD cooler with a “different” orientation

The successor to the SSD cooler, which didn’t have much competition in its price range. That’s one way to introduce the Gecko Pro, which is a bit more expensive, but also more refined (in terms of mounting as well). And it also has a distinctive feature that clearly distinguishes it from other coolers – the fins are not longitudinal (as is common), but in width. The price to cooling performance ratio is again excellent. Read more “Akasa Gecko Pro: An SSD cooler with a “different” orientation” »

  1. Although the test a super, non of the recommended Fans can be bought today making it intentesting but overal not that usefull. For next test, please include some fans that are expeded to be solf for at least one year later.

    1. The selection of older, outdated fans for this test was purposeful. The goal was to get some results/ some basic idea to have something to go off of when evaluating current fans. When you look at the current database, it overwhelmingly contains fan models that are widely available in stores: https://www.hwcooling.net/en/bequiet-light-wings-bl072-sturdy-rotor-with-argb-leds/13/

      The first eight have been selected so that later on none of these models will lack (since they are no longer sold) an in-depth evaluation of all aspects, as we do at the end of the “solo” tests, of which there are 26 after this article.
