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 33.3 dB(A), an external sample table helps to break it down.
Benchmarks
For the first run, the Fuma 2 Rev. B is tested with two fans, as intended by the manufacturer:
2 fans |
30% PWM |
60% PWM |
100% PWM |
Fan speed (front) |
440 RPM |
978 RPM |
1509 RPM |
Fan speed (center) |
633 RPM |
1113 RPM |
1501 RPM |
Sound level |
33.5 dB(A) |
36.8 dB(A) |
43.9 dB(A) |
Ambient temperature |
20,5 – 21,2°C |
21,5 – 21,8°C |
21,9 – 21,9°C |
And even though there should actually not be a compatibility problem with the RAM thanks to the thin Kaze Flex II Slim at the front, here is still a test series with only the thicker center fan:
1 fan |
30% PWM |
60% PWM |
100% PWM |
Fan speed (center) |
635 RPM |
1177 RPM |
1698 RPM |
Ambient temperature |
22,1 – 22,4°C |
22,6 – 22,6°C |
22,7 – 22,7°C |
And that’s how Rev. B fares against the original and other comparable coolers:
