My 3600 is constantly running at 1.4 to 1.43V idle, in stress tests it gets up to 90 degrees and I stop the test. I can switch to a non-stock cooler, but I know this issue is common. Switching to windows power plan doesn't seem to help (I might need to restart though).
I'm on stock bios settings apart from enabling A-XMP. My mobo is an MSI B450 Tomahawk Max with latest bios. I'm using stock cooler, but I'm switching cooler if this isn't fixed, so even though voltages are high it won't overheat.
Both CPU-Z and Ryzen Master read the same high voltages with no other programs open. I'm on chipset 1.7.29.0115.
