DeepCool Assassin IV Review – Can it beat the Noctua NH-D15?

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

20_dBA_CPU_Frequency

25_dBA_CPU_Frequency

30_dBA_CPU_Frequency

Full_Fan_Speed_CPU_Frequency

The average CPU frequencies are very close to the ones the Assassin III achieves.

CPU Wattage

20_dBA_CPU_Watt

25_dBA_CPU_Watt

30_dBA_CPU_Watt

Full_Fan_Speed_CPU_Watt

The CPU wattage is high, meaning the cooler allows the CPU to deliver more workload. Moreover, the watt readings I got from Powenetics are at the same level as the Assassin III.
