Test setup and results …
For the practical test, we have mounted the Cooler Master MA620P on our new AM4 test system, which consists of the following components:
ASRock Fatal1ty AB350 Gaming K4
AMD A8-9600 @ 3.8 GHz with 1.4 Volt
4GB DDR4-2400
Cooler Master Testbench v1.0
For measurement, the following tools were used: Prime95 and SpeedFan
Thermal compound: Cooler Master Mastergel Pro (included)
The ambient temperature during the test was about 21°C.
The Cooler Master MA620P also competes against the AMD Boxed Cooler, but you may also want to check out our recently released test of the Cooler Master MA410P and the Cooler Master MA610P that was tested under the same conditions and compared the results.
We then used the CPU for 30 minutes with Prime95 and recorded the temperatures.
The Cooler Master MA620P naturally beats the AMD boxed cooler in terms of both temperature and noise level.
But to make the dual-tower cooler also a fair challenge, we have also let the Noctua NH-D15 against it.
Here the MA620P must indeed admit defeat at the temperature, but can take points at the top volume.
The fan volume is measured with a dB meter from 100cm distance. In addition, we determine the respective rotational speed.
| Cooler Master MA620P | ||
| 20% | 33dB | 626rpm |
| 40% | 34dB | 740rpm |
| 60% | 35dB | 1061rpm |
| 80% | 38dB | 1338rpm |
| 100% | 41dB | 1551rpm |
The fans make a usual good impression. Up to 40% perfect for silent settings, 60% is in the middle range and 80% is a bit louder but still OK. The jump to 100% is then a little bigger, this attitude should be avoided, at least as a silent lover, since the cooling performance does not increase to the same extent. The fan noise is free of disorders.
To be able to estimate the fan noise, there is also a video as usual:
