CPU Overheating in Windows 11

Dialing down the Maximum Processor State to 99% in Power Plan no longer works for me. It worked for a while but as soon as there's a major Windows Update, it's broken again. Right now, I have it dialed down to 75% to keep the temps in the 70 - 80 range while gaming which is still on the high-end if you ask me but if I leave it at default (100%) I've seen it shoot up into the 90s quickly. And yes, apps, browsers, and things load a bit slower naturally.

In my opinion and as someone that's worked with Windows for decades in an IT environment, this is related to how they implemented Virtualization and the Core Isolation features in Win 11.

Again, I've had 0 issues while on Win 10 and with Win 11 for a long while. As soon as I installed the 22H2 build of Win 11 this started happening immediately.

I'm seriously contemplating going back to Windows 10. It is absurd that Microsoft doesn't recognize this as an issue and blames the users for having "dirty fans" and such.

The most shocking part of this issue is how the fans go absolutely crazy at the Windows Logon screen upon powering on the PC. As soon as I log in, I check the Task Manager for anything hogging the CPU/Memory but there is nothing. Then the temps and fans naturally dial themselves down after a few minutes of normal PC activity but if I try gaming, it goes berserk again.

I'm shocked to see these overheating problems in Windows 11! I've stumbled across these posts here after searching for problems with overheating in Win-11.

I started having an increased amount of random bursts of the CPU overheating maxed out fans in the last few weeks which became very frustrating (also occurred intermittently few times inside the last 4 months too).

My system is just 6 months old - The CPU issues only occur when windows 11 is booted. The PC starts up and as soon as Windows logo appears the fans all kick in 90-100% speed with temps running around 80, 90 and sometimes 100+. Changed to another new AIO pump and exact issue repeats! Everything is clean.

Like you have said on your final paragraph I can relate 100% to this noticing the pattern: Logon screen to signing in they all ramp up full for 1-2 mins before settling down. While this occurs the task manager CPU isn't really being used. Didn't try gaming just yet since I mostly use it for SQL work etc.

On the odd day just suddenly at any random time the PC the fans will just go max for no reason and no task manager items seem to relate to why. Even closed multiple tasks down but no help. The Balanced Power setting with 99% CPU doesn't help but, a little while ago 50% helped and not any more.

this fix worked for me, Thank you so much!!

As I said earlier in this thread, I had the same problem. I found the problem went away if I throttled my CPU to 99%. If I put it to 100% the CPU often overheats and shuts down my system.

To throttle: Start>Search bar enter "Edit power plan">Change advanced power settings>Processor power management>Maximum processor state>Plugged in: 99%.

Solved the issue for me. Running Asus Vivobook 16, Windows 11 Pro, AMD Ryzen 9 5900HX with Radeon Graphics @ 3.30 GHz

solved.

I noticed that after updating to Windows 11, some drivers from the previous windows 10 OS were also running in the background.

purged the old drivers, temp files, dump logs etc. and now running idol at 104F/40C. Gamming at 165F/74C.
