Cooler Master MasterLiquid 360 Atmos CPU Cooler Review

Cooling Performance & Testing

Thermal Testing – How does Cooler Master’s new Atmos Cooler stack up?

As always, our CPU cooler testing has been conducted on an overclocked i9-9900K that is clocked at 4.8GHz at 1.2V. Using this configuration, we test the thermals of our processor using various CPU coolers. These tests were heavy loads, using OCCT for 30 minutes. The charts below shows the data we have gathered.

Thermally, Cooler Master’s new MasterLiquid 360 Atmos is one of the best performing CPU coolers that we have tested. Using this unit’s fans at their highest RPMs, the Atmos 36o is the best heatsink that we have ever tested. That said, these fans do max out at 2450 RPM, which is on the loud side.

For the Atmos 360, we had to forgo our usual 600 RPM fan test. The reason for this is that these fans simply do not spin when we run them at 600 RPM. Cooler Master’s SickleFlow Egde 120mm fans cannot run at such low RPMs. That said, this is a ridiculously slow fan speed. 1000 RPM fans speeds are plenty quiet if you are worried by potential noise levels.

At 1000 RPM and 1500 RPM, the 360 Atmos sits amongst the best performing heatsinks on the market. There are many heatsinks that require much faster, and noisier, fans to deliver these thermals. The 360 Atmos is a solid liquid cooling solution.
