Speed and noise
Fan speed :
We’re starting from scratch with our series of temperature readings. Let’s specify the fan speeds recorded during our readings (for 12V, 8V, 5V):
As far as fan speeds are concerned, we’re dealing here with particularly fast mills. At full speed, they reach 2400 rpm, compared with 1000 rpm at low speed. At mid-range, with 66% PWM signal, we record 1600 rpm.
Noise :
As for noise, at full speed the kit proves to be particularly noisy, as we recorded 49.5 dB. That’s a far cry from the 39 dB of a Liquid Freezer II 420… Fortunately, as soon as you adjust the fan speed, you can significantly reduce the noise level. At 1600 rpm, we’re down to 37.5 dB, while the fan will be inaudible at low speeds… OUF!
