Normalized Noise Tests
For these tests, I set the cooler’s fan(s) to speeds with noise output at the following predefined levels: 20/25/30/35/40 dBA. I skip the corresponding tests if the cooler’s fan(s) cannot reach some noise levels. Finally, I include a test where the cooler’s fan(s) spins at full speed.
I provided the PWM controller’s readings in this chart, taken by all fans using the provided Y splitter.
CPU Temperature
The A115 has the lowest CPU temperature at full speed because it is the noisiest one. At 30 dBA, it loses to the Cooler Master MA824 and the Noctua NH-D15, though not by a large margin.
CPU Frequency
The NH-D15 offers the highest CPU average frequency speed from the air coolers. The A115 performs well here.
CPU Wattage
Close to 330W at 20 dBA, 338W at 25 dBA, 348W at 30 dBA, and above 350W at 35 dBA and full fan speed.
Cooler Exhaust Temperature
I measure the temperature at the back side of the air cooler.
“Lower is better” in “Average Watt” chart: is it correct?
