Introduction : About a week ago now, my CPU started idling around 60-70C with nothing open. It used to be around 50C - I have sufficient airflow in my case (Meshify C).

Hi, please reboot your system and check your cpu voltage in the BIOS. I had an issue that caused the XMP profile to set voltage to be at 1.45V for the ram profile, but it also changed the cpu voltage to be above that value. You can also use the CPU-Z to check it when you will boot up your Windows 11.

I tried disabling XMP in BIOS, however it did not solve the problem - thank you for the suggestion though. QuantumXenon Please check your benchmark score on the CPU-Z, as if it is throttling your score will be lower than it should be. The AMD Ryzen Master seems to not work well on Windows 11, and it detects my system as Windows 10. I may be wrong, but disabling the xmp alone will not change the cpu voltage if it was set at certain value. I am on the asus motherboard with the ryzen 3800x, and using the auto voltage can cause that issue, the cpu should thermal throttle at the temperature you seems to get.

CPU Overheating in Windows 11

Introduction:

About a week ago now, my CPU started idling around 60-70C with nothing open. It used to be around 50C - I have sufficient airflow in my case (Meshify C). I don’t remember installing any programs or updates around this time - in fact I think it started while I was in the middle of using the computer. It had been running fine for around a year.

Problem:

When I boot into Windows, all fans ramp up to full for a bit, then calm down.
My idle temperature with nothing open is 60-70C, and maxes out at 80C if I put it under load.
When I open some applications, the fans ramp up to full for a bit

So far, I have:

Reseated CPU/AIO
Dusted my computer
Replaced thermal paste (MX-4)
Reset BIOS
Cleared CMOS
Done a fresh install (where it was still overheating before installing anything)
Run Windows Memory Diagnostics (no problems)
Changed power plan to balanced
Run chkdsk (no problems)

Other Information

When in Safe Mode, the fans don’t run as high (so I assume that the temperature is fine, but I can’t tell because monitors don’t work)
I didn’t have temperature problems in Ubuntu MATE when I checked with lm-sensors
I have no overclocks except for XMP on the RAM
