Our Tests

The table below presents the results of our measurements. We repeated the same test on each cooler listed below, with the CPU at full load. The fan speed was adjusted in the motherboard setup to automatic control.

As we are comparing the temperature difference between the CPU and the air outside the computer (and not the actual CPU temperatures), there is no bias in taking measures under different room temperatures. Both heat transfer physics and our practical tests proved this.

 

Cooler Room Temp. Noise Fan speed Core Temp. Temp. Diff.
AMD Wraith (full)
14 °C 49 dBA 3.000 rpm 62 °C 48 °C
AMD Wraith (auto) 14 °C 44 dBA 2,200 rpm 68 °C 54 °C
AMD Stock
13 °C 52 dBA 4,700 rpm 69 °C 56 °C
Cooler Master Hyper 212 EVO 14 °C 45 dBA 1,500 rpm 50 °C 36 °C
PCYES Zero K Z3
13 °C 42 dBA 1,400 rpm 67 °C 54 °C

On the graph below, you can see who many degrees Celcius the CPU core was hotter than the air temperature. The smaller the difference, the better is the cooler.

 On the following graph, you see how many decibels of noise each cooler makes. The lower, the quieter.
