Our database now includes one hundred fans—75 in the 120 mm format and 25 models with a physical size of 140 mm. In this article, we have compiled all data into unified charts. What was once separated for clarity is now brought together again, and the commentary will also include a… look ahead regarding fan testing. But we can already reveal that there is still a lot more to come.
Measuring the intensity (and power consumption) 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.
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 consumption 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 consumption. In the graphs we show it separately, but also in sum with the motor power consumption as the total maximum fan power.
Thank you for all the hard work in reviewing and compiling this information!
If it’s not too much effort, would it be possible to maintain a page like this going forward with each new reviewed fan added on? It’ll make a convenient location to be able to reference back to (a one-stop-shop if you would).
Thank you for the comment! 🙂
What exactly do you mean by keeping it the same as in this article?
We separated the 140 mm fans from the 120 mm ones to prevent the charts from becoming too long. Even as they are now—especially in the 120 mm category, where we have more models—the graphs already take up quite a lot of vertical pixels. If combined, navigating them would be rather inconvenient, even on high-resolution monitors
Great job, guys.
Thank you! 🙂
