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)

    Today I did a test again by rolling back my windows 11 back to an system backup dated 14-01-2022. System idle temp is 44C.

    Updated the below updates and idle CPU temp becomes 78C-83C. I think either KB5010474 or KB5010414 is causing the issue.

    Windows 11 Pro (22000.434) + below updates works fine. If you upgrade to latest, then issue will start.

    I have exactly the same issue that QuantumXenon is facing. I updated the Windows 11 on 30-01-2022. Issue started after that. Till 30-01-2022 PC was having an idle temp of 47C win Win 11. The PC was running fine without any issues for 4 months (Both Windows 10 and 11)

    After the Windows update on 30-01-2022 the Windows 11 PC started showing a CPU temp of 71 and eventually went up to 84C in idle state. Simply switching the OS to Win 10 brought down the idle temp to 44C. Definitely its a Windows 11 thing
