PWM Performance

Temperatures

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 ajust the fan speed via PWM signal according to CPU temperature. The idle temperature is the lowest temperature hit by the processor package after 10 minutes idle. The load temperature is the highest temperature hit by the processor package after one pass of wPrime v2.10. The wPrime test takes 4 minutes puts load on all 8 threads. Room temperature is 25°C.

Fan Speeds

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

Noise Levels

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.
