We measured the acoustic readings off Asus coolers in their default configuration and Thermalright IFX-14 with one Noiseblocker fans in the entire supported rotation speed range. Here are the results:
Unfortunately, the fans on both Asus coolers turned out pretty noisy even at their low rotation speeds. Besides, the fan of Axe Square AMAzing crackled and the fan of Triton 88 buzzed in the rotation speed interval between 950 and 1400 RPM and rustled at the speeds below 950 RPM. Overall, we have to admit that these are not the best fans. I have to also mention that the startup fan voltage by Axe Square AMAzing is 4.0 V and by Triton 88 – 6.8 V.
