Chad's CPU Cooler Test System Specifications

To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article (October 2016) for more information.

Thermal Results


Allowing the PWM controls to do their thing, our stock test runs on this cooler has the Mugen 5 Rev.B able to deliver a result of 56 degrees. While the chart appears to not favor that result, keep in mind that it runs neck and neck with the NZXT Kraken X52 while was in performance mode.


Still allowing for PWM control of the fan, the overclocked results chart tends to show the Scythe cooler in a better light. Sixth place overall at 70.75 degrees is quite the feat and stands near the top in some great company.


Looking for the most the Mugen 5 Rev.B can deliver, we see that the PWM curve set for the fan is nearly top of the range. Forcing the fan to run on 12V shows us that we can only gain half a degree improvement, which means Scythe did a near perfect job with the setup and development of this tower and fan combination.

Noise Level Results


At all time, we found the fan of this cooler to idle at 400 RPM, with little more than a slight "whir" heard when you are right on top of the fan. From a foot away, while the fan topped at 637 RPM for this reading, we only saw 25 dB on the meter at that time.


When we took this 28dB rating during the PWM controlled overclocked run, we saw the fan spinning at 806 RPM. So far, with both tests, the noise level is under control and leaves the Mugen 5 Rev.B at the top half of the charts.


The 30dB result when forcing 12V through the fan is the best we have seen so far. What is strange about this, not so much for noise, but spinning now at 1084 RPM, we would have expected slightly better performance than just half a degree of difference.
