Cooler Master MasterAir G100M Review

Test setup and results …

For the practical test, we have mounted the Cooler Master MasterAir G100M 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 (included)

The ambient temperature during the test was about 21°C.

The Cooler MasterAir G100M competes against the AMD boxed cooler.

If you want, you can also join our recently published tests of the Cooler Master MA410P and the Arctic Freezer 12 that have been tested under the same conditions and compare their results.

We then used the CPU for 30 minutes with Prime95 and recorded the temperatures.

The Cooler MasterAir G100M struggles hard against the AMD Boxed cooler. In the mid-speed range, it is just slightly superior to the AMD cooler, but in the upper speed range, it is narrowly beaten. We were so surprised by the results that we even completely uninstalled the G100M and reinstalled it to start a second test run, but were only able to confirm the measured results.

At less than 40% speed, the temperature also climbed above the 70°C mark, beyond which the overclocked A8-9600 APU clocks down autonomously.

The fan volume is measured with a dB meter from 100cm distance. In addition, we determine the respective rotational speed.

Cooler Master MasterAir G100M
20% 34dB 730rpm
40% 35dB 963rpm
60% 36dB 1359rpm
80% 37dB 1718rpm
100% 40dB 2085rpm

The fan also gives a rather mixed impression. Up to 40% it is still passable for Silent Settings, 60% and 80% are already louder, but still OK. The jump to 100% is then a little bigger again. From about 60% you can also hear another noise, which can not be heard from a closed housing.

To be able to estimate the fan noise better, there is again a video:
