Methodology
An AMD Ryzen 9 3950X has to be cooled at various power consumption levels, along with 16GB of Crucial Ballistix Sport (2x8GB) DDR4 RAM on an MSI B550 Tomahawk (BIOS 7C91vAB). The Asus ROG Strix GTX 1060 6GB runs for the CPU stress tests only for the image output in zero-fan mode and a Fractal Design Ion Gold 750W serves as the power source. The whole thing is located in the Thermaltake Core P3 as an open benchtable.
The test system runs on Windows 10 Pro 22H2 (Build 19045.2251). All data sets are recorded with HWInfo64 v7.34-4930 – 5000ms logging, the specified temperature results from the CPU Die (Average) sensor. Since I don’t have air conditioning, the values in the graphs are the delta between room temperature and CPU temperature. This means that all cooling systems can be compared fairly, even if the ambient temperature is different. The heat-conducting paste supplied with the cooler or applied beforehand is used in each case.
I determine the sound level with a Voltcraft SL-200 measuring device at a distance of 40 cm, which works in 125 ms cycles in Lo mode. The room was measured at 33.2 dB(A), an external example table helps to break it down.
Benchmarks
There is only one test run today, as the built-in fan only reaches 39.6 dB(A) even at maximum speed. Although this consistently low noise level is pleasing, the cooler can no longer keep up at 200 watts load.

Summary and conclusion
As already mentioned, the Pure Rock 2 was unable to complete the last test at maximum load without some thermal throttle or automatic reduction of the power target.
As a result, it ends up at the bottom of our ranking. All the more curious that at the time of publishing this article, this model is the #3 most popular air cooler at geizhals.de and receives consistently good reviews from buyers. I think this shows that the vast majority of people don’t have a 200 watt beast in their computer, but rather a handy mid-range processor. Coupled with a 3-year guarantee and a well-known brand, even a mediocre offer from the budget sector can become a bestseller.
