SilentiumPC Fera 3 HE1224 V2 CPU Cooler Review


Performance of the SilentiumPC Fera 3 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 Fera 3 during a typical workload is able to keep our processor at about 76°C. It’s not the best but pretty good result considering the cooler’s design. The maximum temperature was already 92°C but still below throttling point of the CPU.

The 3000 Ryzen processors are generating a lot of heat, so maximum temperature above 90°C is nothing surprising. Our comparison includes two coolers which couldn’t handle the 3700X. It’s Cryorig C1 and stock AMD cooler. Both were reaching 95°C at which we could see thermal throttling and significant performance drop.

Our tests are showing that Fera 3 is a perfect replacement for an AMD stock cooler. SilentiumPC Fera 3 helps to keep the optimal performance of the Ryzen 3700X.

The additional advantage is generated noise. The Fera 3 is really quiet, and even at a higher fan speed, it’s a better option than the AMD cooler. Our test rig noise during mixed load tests was around 35dB, including graphics card and chipset fans.

Since the new AMD is generating a lot of heat then is not easy for overclocking. On the other hand, manual settings let it overclock at a lower voltage. Our perfectly stable result is 4200MHz on all eight cores and 1.30V. The manual setting gives us about 2°C lower temperature and slightly better performance than the automatic AMD setting.
