Temperatures
All temperature charts are sorted with lowest load temperatures at the top.
The MA620P is quite a competitive air cooler. It may not seem that high up the charts, but once you get into the top third of our cooling charts, the margins become very fine indeed – an extra two degrees is all that separates the MA620P from being in the top five coolers.
It also beats a couple of liquid coolers as well – the Deepcool Captain 240 EX RGB, for instance, can't cool as well. Overall, the MA620P is Cooler Master's best performing air cooler that I have seen to date.
Acoustics
It's also a quiet cooler, with idle noise being essentially non-existent. Even when under full load, with the CPU at stock clocks, the fan noise is barely audible.
Once our CPU overclock was applied, we did hear a bit more of a whirr from the MA620P, but even then I have heard much worse from the likes of the ID-Cooling FrostFlow.
