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.
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.
