Methodology
A Ryzen 5 3600 has to be cooled at factory settings, joined by 16GB Crucial Ballistix Sport (2x8GB) DDR4 memory on an MSI B550 Tomahawk (BIOS 7C91vA9). The Asus ROG Strix GTX 1060 6GB runs in zero-fan mode for the CPU stress tests only and a Fractal Design Ion Gold 750W serves as the power source. The whole thing is housed in the Thermaltake Core P3 as an open benchtable.
All data sets are recorded with HWInfo64 v6.30-4240 – 2000ms logging, the specified temperature results from the sensor CPU Die (Average). The load of Prime95 produces an average of 88 watts of CPU package power. Since I don’t have air conditioning, the values in the graphs are the delta between room temperature and CPU temperature. This allows all cooling systems to be compared fairly, even if the ambient temperature is different. The thermal paste included with the cooler or pre-applied is used in each case.
I determine the sound level with a Voltcraft SL-200 meter at a distance of 40cm, which operates in 125ms cycles in Lo mode. The room was measured at 33.2 dB(A), an external sample table helps to break it down.
Benchmarks
To make the results as comparable as possible, I first put the old revision of the cooler on my testbench. Both coolers were tested with the same tube of Arctic MX-4 thermal paste to rule out variances in the included thermal paste.
1 Fan – Rev A |
30% PWM |
60% PWM |
100% PWM |
Fan speed 1 |
545 RPM |
1019 RPM |
1465 RPM |
Sound level / characteristic |
33.5 dB(A) |
35.6 dB(A) |
42.7 dB(A) |
Ambient temperature |
24,7 – 24,8°C |
25,0 – 25,2°C |
25,7 – 25,7°C |
And here are the long-awaited results for the revised Rev. C of the Mugen 5 Black Edition:
1 Fan – Rev C |
30% PWM |
60% PWM |
100% PWM |
Fan speed 1 |
586 RPM |
1045 RPM |
1474 RPM |
Sound level / characteristic |
33.4 dB(A) |
35.9 dB(A) |
43.4 dB(A) |
Ambient temperature |
25,1 – 25,0 |
25,5 – 25,2°C |
25,5 – 25,5°C |
And this is how the improved Revision C fares against the old variant as well as other coolers in the same price segment:

Summary and conclusion
Now that’s something we like to see around here! The faults in a product are (belatedly, but at least) recognized and corrected. And already a product that I could only advise against becomes one with competitive performance in its price range.
And so I can attest to the Rev. C of the Mugen 5 Black Edition a good cooling performance with pleasantly quiet operation. If you already liked the look of the inconspicuous cooler, you can finally buy it without a guilty conscience.
The test sample was provided by Scythe without obligation. There was and is no influence on the tests and results. There was also no compensation for expenses and no obligation to publish.
