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


Considering the lack of fan speed and noise for this test, the 57.25-degree result is admirable. The Fuma Rev.B is less than 6-degrees from the lead, and is only slightly more than two degrees behind the flagship NH-D15, with much less size involved with this Fuma Rev.B.


72.25-degrees may look average on the chart, but put things into perspective. Is it only a couple of degrees warmer than the D15, it keeps up with a few of the 240mm AIOs on this chart, and sticks to that six degrees or so behind the best cooler we have tested.


Scythe does leave a bit of meat on the bone moving from PWM to DC control of the fans. In the testing we did, the fan increased 500 RPM without a bunch of added noise, and took the overall temperature down to 69.25, just a tad more than four degrees from the lead.

Noise Level Results


While we ran the stock test, we kept an eye on the fan speed, as it peaked at 750 RPM. At that speed, we took our measurement and saw 23 dB on the meter. It does not get much better than this and is how Scythe can tie for second place.


Even with the heat from the overclock demanding more of the PWM fan circuit, the speed only increased slightly. 990 RPM was the maximum seen at this time, and the noise increased, but just barely, to just 25 dB.


Pushing the fans to their full capabilities did improve performance a fair amount, at 1480 RPM, the amount of noise produced is more than acceptable. Only 31 dB of noise is heard in an open-air environment, and with a closed chassis, it is highly likely that the Fuma Rev.B will not be heard.
