Performance
Performance of the Scythe Fuma 2 cooler has been tested on the latest AMD Ryzen platform. Used Ryzen 7 3700X processor, even though that has declared 65W TDP then heats up a lot so is a challenge for any CPU cooler.
For tests, we’ve used the ASRock X570 Extreme4 motherboard and default AMD settings.
All tests were performed on an open test rig. The ambient temperature was about 24-25°C so quite high for a room, but well, it’s summertime.
Our comparison includes three tests. The idle mode is a PC left without any load besides standard Windows services running in the background. The mixed-mode base on a PCMark 10 extended test which uses popular applications and simple games. The max load is a CPU+FPU AIDA64 stability test. Shows about maximum CPU load during the most demanding work on all CPU cores. A maximum load test can also be compared to a popular Prime95 small FTT test.
The Fuma 2 is so far the best non-water cooler in our tests. It’s about 2°C better than the Noctua D9L with two fans which is smaller but also needs to run at its full speed to keep high performance. The Fuma 2 performs great and runs really quiet at the same time. Generated noise is close to that of 240-280 AIO coolers, but it also takes less space. Mixed load tests on our test rig were showing about 34dB what is an excellent result considering that in 3D tests we could hear graphics card’s fans more than the Fuma 2.
In time we will add more coolers to the comparison so I guess it can be more interesting. On the other hand, I wouldn’t expect much better performance on the Ryzen 3000 series unless we decide on water cooling which costs more and requires more space in the PC case. These processors simply run hot what isn’t so obvious looking at their specified TDP.
Scythe Fuma 2 has some thermal headroom if we wish to overclock our CPU. The 3700X could run at 4.3GHz on all cores what is 100MHz more comparing to previously tested SilentiumPC Fera 3. Also, supported voltage under constant load went up from 1.30V to 1.37V. Users with more luck can count on 4.4GHz at the same voltage, but even our result is above average, so we are fully satisfied.
