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|
||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.
