It is not an easy job when it comes to evaluating the performance of coolers on new platforms from Intel and AMD. The AM5 platform by design will run at its full thermal limit, providing the maximum headroom for high frequencies though this is something which the community did not take positively. Any cooler that you will install on this platform, will result in CPU temperature hitting 95°C under load. We have found that setting the CPU at 5.2GHz would actually result in lower temperature under heavy load. Other way is to use PBO profiles and load a lower Watt or lower thermal limit settings.We run the CPU at its stock settings and examine the behavior of clocks under heavy multi-core load using CINEBENCH R23.2. The temperature was at 95°C but this cooler maintained 4700MHz during a 30-minute run on all cores. We can say for sure that at some point in time, the frequency will fall below the base clock which is subject to length of that software run and the load type.Single-Core load was good as we did not see any performance drop. It was simply due to the fact that CPU was boosting to 5.45GHz on any core. Maximum temperature recorded during a single-core load was 65°C. We then loaded Assassin’s Creed Origins and played it 1080P resolution using Ultra High graphics settings. We saw a maximum temperature of 80°C during the game play.
