All tests were run in our custom built computer to best reflect real life performance. The computer remained in the same place and room for all tests. The ambient temperature of the room was roughly 22 degrees Celsius. The thermal paste applied to each cooler was stock respective to their manufacturer's to rate its performance. Sufficient time between testing was applied for the paste to settle. The fans on all heatsinks were connected to the same motherboard 4-pin connector. The test computer was turned on and 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 eight worker threads for a minimum of fifteen minutes and recorded when the temperature was deemed stable. The Cooler Master MasterAir G200P was tested using the stock fan from factory. The performance was compared with an air cooled CPU cooler from Cooler Master, the Cooler Master Hyper 212 EVO. The purpose of doing such tests was not for a straight performance competition, since they were quite different in terms of design and fan size; it was for a performance perspective. The temperature results for each cooler was measured with CoreTemp, 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.

In the idle test, the two coolers had similar results. The MasterAir G200P stabilized at 39 degrees Celsius. It was a pretty good result, considering the room ambient temperature was around 22 degrees Celsius. The temperature at idle state differed slightly between the MasterAir G200P and the other cooler. The Hyper 212 EVO only brought the temperature down one degree lower than the MasterAir G200P. At idle state, the Hyper 212 EVO performed very slightly better than the MasterAir G200P, despite the low profile design of the latter. These results suggested that, at idle state, the MasterAir G200P delivered as expected despite its small size.

The real challenge happened when the CPU was working at high load. Along with the increased processing speed of the CPU, the fan’s RPM also reached the maximum. After about thirty minutes, the MasterAir G200P kept the temperature constant at about 89 degrees Celsius. Today’s review unit resulted in 21 degrees Celsius higher CPU core temperature compared with the Hyper 212 EVO. Please note regarding the single fan performance, the maximum air flow of Hyper 212 EVO's stock fan is much higher than the 92mm fan used by MasterAir G200P and the heatsink of Hyper 212 EVO is significantly larger than the MasterAir G200P. Therefore, there is no doubt that the Hyper 212 EVO can outperform the MasterAir G200P. However, as you can see above, the resulting CPU temperature of the MasterAir G200P is reasonable for a low profile cooler. For CPUs with a lower thermal design power, the the MasterAir G200P will be able to deliver much better results. All in all, the MasterAir G200P has the ability to keep a CPU reasonably cool as an ultra low profile cooler, even in a bad case scenario like having an Intel Core i7-9700K.

I am the kind of person who really cares about the noise level of my computer. On a scale of 0 to 10, where 0 is totally silent and 10 is a jet taking off, I would rate the the MasterAir G200P at 2.0/10 and 4.0/10 regarding noise emissions at idle and high load, respectively. The 92mm PWM fan was reasonably quiet at lower speeds. However, the fan can be a little bit noisy at higher RPM. It is worth mentioning that the fan can spin as fast as 2600 RPM, which is necessary for a fan of such a small size. If you are not happy with the noise of the fan, at least the RGB lighting looks good here, haha.

After all the tests were done, I would like to say that the MasterAir G200P is a well-balanced ultra low profile CPU cooler with a 92mm RGB fan. This is because it had acceptable cooling performance as measured above considering a relatively high power CPU and acceptable subjective test results regarding noise level. Moreover, you can practically put this cooler into almost any computer case on the market.
