At this point we plugged the fan(s) to the motherboard CPU fan header and let the
motherboard take care of fan speeds. In other words the motherboard will
adjust the fan speed via PWM signal according to CPU temperature. The idle
temperature is the lowest temperature hit by the processor after 10
minutes
in idle. The load temperature is the highest temperature hit by the
processor after one pass of wPrime v2.10. The
wPrime test takes 4 minutes puts load on all 8 threads.
Room temperature is 25°C.

Values are in RPM, we took the lowest speed hit by the fan(s) in idle and the
highest under load.

Decibel meter (Voltcraft SL-200) has been placed 1 meter away from the
cooler. Measurements are conducted in a quiet room, where there are no other noise source. 32 dBA is the lowest
we can get in our room. Also here
the measurements are conducted at lowest and highest fan speeds in idle and
under load respectively.
