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

System Specs

  • Ryzen 9 5900X
  • NViDIA RTX 3070
  • MSI X570 Gaming Pro Carbon WiFi
  • MSI CoreLiquid 360R
  • 32GB Corsair Vengeance RGB Pro
  • Sabrent Rocket 4 (500GB)
  • Windows 11 Pro (22000.434)

    All right, one more thing to add. If you are using Phone Link app (that connects cell phone to your PC) try to temporary exit it / disable / uninstall.

    Then check if this fixed your high CPU usage while idle.

    I'm not promising it will help you but try and disable indexing and see if that helps. There are a lot of people with indexing problems wince W11 and many complaining that indexing is causing high CPU usage and overheating.

    It worked for me. I have a Ace Helios 500 Gaming laptop and never had an issue with W10. With W11 the CPU would be 95c just browsing the net the whole system would sometimes shut down for protection.

    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.
