Test and methodology
A Ryzen 5 3600 has to be cooled at factory settings, in addition 16GB Crucial Ballistix Sport (2x8GB) DDR4 memory on a MSI B550 Tomahawk (BIOS 7C91vA3). The Asus ROG Strix GTX 1060 6GB is running in zero-fan mode for the CPU stress tests only for the image output, and a BitFenix Whisper M 450W serves as the power source, all housed in the Thermaltake Core P3 as an open benchtable.
All records are logged with HWInfo64 v6.30-4240 – 2000ms logging, the specified temperature is derived from the sensor CPU Die (Average). The load of Prime95 produces an average of 88 watts of CPU package power. Since I don’t have air conditioning, the values in the graphs are the delta between room temperature and CPU temperature. This allows all cooling systems to be compared fairly, even if the ambient temperature is different. The thermal paste supplied with the cooler or pre-applied is used in each case.

The second run is done with the middle 140mm fan only, in maximum RAM compatibility mode, so to speak:

Compared to other coolers, the Grandis 3 can definitely hold its own, but doesn’t deliver any surprises either. The second fan in the front doesn’t really make a difference from the medium speed range onwards, but can still make an impressive difference especially in silent mode.
Conclusion / Summary
We have a classic case of “buttered bread” here. Not special, but still perfectly fine and serves the purpose. Even if SilentiumPC can’t get top marks, it doesn’t make any major blunders or problems. The temperatures of the mid-range CPU tested here are on par with somewhat smaller coolers, whereby the specified 250W TDP cooling capacity can then flex its muscles with stronger processors.
According to the manufacturer, the cooler is designed for systems with up to 12-core CPUs, which is probably where the large coldplate comes from. However, the rather low price makes it interesting for standard systems as well, provided an appropriate case is available. If you are looking for a good (and cheaper) alternative for the often sold out Scythe Fuma 2, you have found a little insider tip here.
