Same exact issue after upgrading to 22H2 build of Win 11. I wish I'd never done it. My PC fans were barely ever audible and now when restarting and at the login screen it sounds like a jet engine is about to take off. CPU temps ramp up extremely high when gaming going as high as 95-99 C.
After weeks of tinkering, I found that it has something to do with Virtualization and/or Core Isolation > Memory Integrity. I turned off Memory Integrity and also checked on Virtual Machine Platform option from Turn Windows features on or off. Did a restart and my temps went back down to even when gaming they were around 50 - 60 C.
Things stayed like that for a while until I updated my Nvidia drivers and did a restart. Now the issue is back and have been trying to apply the same fix for days without success.
Oh, and mind you, this is AFTER doing a clean install of Windows 11 as suggested which fixed nothing.
Extremely pissed off! This isn't a case of dirty fans or poor cooling issue. My PC is nearly dust-free and in a clean environment on top of my desk. The issue happened as soon as I upgraded to 22H2 and is clearly a Windows 11 issue.
