All tests were run on our custom-built computer to best reflect real life performance. The computer remained in the same location in the same room throughout all tests. The room temperature in our testing lab was around 22c. Stock thermal paste respective to all coolers were used to rate its performance. All thermal pastes were given a proper amount of time for them to fully settle. The fans on all heatsinks were connected to the motherboard's CPU 4-pin fan header. The test computer was turned on and left idling for at least one hour for the idling tests. High CPU load results were obtained using the Prime95 in-place large FFTs test with a maximum number of worker threads for the tested CPU for a minimum of 10 minutes or until the temperature was deemed stable. Temperature results were measured with HWiNFO, which reports the CPU's integrated digital thermal sensor for maximum accuracy. Each temperature result was calculated by taking the maximum value of the cores inside the CPU.

After letting my computer sit idle for a while, I shook my mouse to wake the computer screen and check the temperature. From the first graph, you can see the Cooler Master MasterLiquid 240 Atmos idled at a temperature of 23c. This was among the coolest results of all of the coolers, which is impressive given this is only one degree above ambient. However, idle numbers do not give a full representation of what CPU coolers can do, so we started up the Prime95 tests to see the more pertinent results.

With more than enough time to load the processor, you can see how all the coolers performed with the peak temperatures recorded. From here, the Cooler Master MasterLiquid 240 Atmos performed well with a maximum full load temperature of 70c. This was the best result we had seen up to this point, matching the notably larger Thermaltake TOUGHLIQUID Ultra 360 AIO liquid cooler. This was also several degrees cooler than the air coolers, which is great to see. Unsurprisingly, the Cooler Master MasterLiquid 240 Atmos was more than capable in cooling off the processor, so we observed its maximum boost frequencies.

As for the sound analysis section, on a scale of 0 to 10 where 0 is silence and 10 is very loud, I would rate the Cooler Master MasterLiquid 240 Atmos at around 4.0/10 under full load. I found everything to be relatively quiet in operation, even when it was moving at full speeds. Of course, it does have more moving parts than air coolers, but everything stayed within reason for its noise output. In more normal usage, this cooling solution was very quiet for an all-in-one cooler and I was quite impressed.
