A small re-configuration of the Fuma 3
What impact does adjusting the fan configuration have on the efficiency and acoustic profile of the Scythe Fuma 3 cooler? We report on the possible changes in the additional tests, where in one of the modes, the heatsink is supplemented with a third fan and in the other we replaced the low-profile fan with a thicker model, but at the same time we deprived the cooler of one of the advertised advantages – the counter-rotating fans.
Spectral analysis of noise
This is a simple analysis at noise levels of 39 dBA, 45 dBA and at maximum speed of the cooler. For the analysis I use the UMIK-1 microphone from miniDPS in conjunction with True Audio’s TrueRTA application. The resolution of the analysis is 1/24 of an octave and the shape of the spectrogram is an average of 100 samples acquired over 20–30 seconds.

Thank you for the review!
For dual tower cooler I prefer to use one in the front and one in the rear.

For the rear fan better use a spacer for less noise.

Might it be possible to replace the slim fan with another SKF 120? Between this and the original test, it’s quite interesting. I am surprised they didn’t give a 3-fan option.
Thanks for the tip for a test. Unfortunately, for lack of time, we will not be able to add it anymore. There are too many things that we are in delay with…
