Thermal Results

It is not hard to see that the 60.75-degree result in this chart is not the best, but it is still closer to the top than it is to the stock Intel cooler performance. Looking at what it is directly competing with, at first looks promising, where we see AIO names right with it, but those results are with quiet mode enabled on them. Looking a bit further up, we see the similarly priced Freezer 33 that we did not care for all that much, which does not bode well for the MA620P.

As we ramp up the demand on the MA620P, it stays in a similar slot on the chart with the 77.25-degree result. Tied with the much smaller Freezer 33 this time, and behind a whole slew of coolers which are as affordable if not more so, and well behind all other dual-tower offerings in the chart.

With the purpose of this test to see what is left in the tank, we see that Cooler Master is giving you most of the performance out of the box, and with little noise, as you are about to see. While the additional two degrees would be pleasant to have and change the outlook of this cooler in the previous test, it takes a ton more noise to accomplish this.

Noise Level Results

Acoustically, we have not a single complaint about the 26 dB results delivered with our stock testing. At idle, the fans rest at 600 RPM making barely a peep, but with the load applied, fans increased to 920 RPM and delivered this result. It is not the best, but far from the worst, and very tolerable in this respect.

Even with the overclock applied, the noise levels do not increase to a range where it got annoying. At just 32 dB while the fans were topping out at 1170 RPM at this time, we like what we are not hearing. Though we would gladly take a bit more noise to gain a couple of degrees with this design, Cooler Master wanted to keep silent, which has hurt performance overall.

As we said, you can gain another two-degrees of performance, but it comes at a cost. To get the best from the cooler, we allowed a constant 12V to supply the fans, where we saw the maximum speed of 1760 RPM. However, at this speed, the noise level jumped to 48 dB, which is a tad loud for 24/7 usage.

After a year of gaming, Chad caught the OC bug. With overclocking comes the need for better cooling, and Chad has had many air and water setups. With a few years of abusing computer parts, he decided to take his chances and try to get a review job. As an avid overclocker, Chad is always looking for the next leg up in RAM, cooling, as well as peripherals.
