R5 3600 operates at 55°C when idle.
Unusual idle temperatures on your 3600 are puzzling. You've checked cooling setup and even swapped mounts, but performance drops under load. It seems the issue might not be the cooler itself. No clear cause identified yet.
If that’s the intended temperature range, it probably just records the highest reading from the HotSpot, possibly due to a small CPU area or a poor mount/paste. - Have you cleaned and re-applied paste after re-mounting? What does hwinfo64 display for idle cores and other temperature sensors on your CPU? On your 5900x running Windows 10 Pro Daily Driver at idle, the package temperature reads 52.9°C because one core is active with the Windows ticker and handling input devices. This might mean Windows is working in the background while you’re idle. If Prime95’s stress test completes without errors for an hour, it’s likely nothing to be concerned about.
