Hi MK, Check your windows update history and see the installed dates of the "problematic" Windows 11 updates I mentioned in the previous post. If the date matches the time your PC showed excess temp, you can conclude.

After installing Windows 11, my PC overheats often. If I leave it idle with nothing running, it will start to generate a lot of heat, even though it is set to automatically go to sleep after 15 minutes. Sometimes it gets really really hot. Has anyone else experience this?

What i did was remove the cmos battery for like 10 minutes and put it back and it half fixed the problem kind of. But mine did that on startup and yes I have the same settings as you do with the 15 minutes thing

I'm using Aser swift 3 i5 8th gen laptop. After installing windows 11, my laptop becomes very hot even if close all the applications. Many background processes run in the background unnecessarily causing this issue. Now I'm just fed up with this Window 11 and switching to Linux (Linux Mint) . I'll never use Windows again in my life. Good bye Windows👋

CPU Overheating in Windows 11

Anonymous

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)
