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 both fans using the provided Y splitter.
CPU Temperature
CPU Frequency
The average CPU frequencies are high enough, in line with other high-end coolers. At full fan speed, the CM cooler stays behind.
CPU Wattage
The CPU wattage is high. The differences with other high-end coolers are low here, although 10-15W can affect the CPU’s frequency.
