Thinking back to my 10900K CPU, it would heat up to a higher temp on all cores when running a manual Windows Defender antivirus scan of the whole OS drive. The OS drive was on an NVME drive.
In coretemp I could see the core usage maxed out on all cores when the antivirus scan was running hard...
Possibly a way to avoid the restrictions Microsoft is placing on the older hardware and still recycle donated computers to people with a familiar OS, at least from their perspective. ***edited***
Bare with me as I am not Linux literate.
Would a Linux install that boots to the desktop, then loads virtual box, then Windows 11 in a virtual PC work.
Unfortunately, the liquid cooling is almost a must for the GPU’s VRAM. I own the Legion Pro 7i Intel w/ Nvidia mobile 4090, a similar 16” thin design. I frequently see VRAM temps > 100C. I am just glad I sprung for the 3 year warranty.
I will go with Sandy Bridge E. My 3930K was the best over clocker I have owned, with a stable 4.6Ghz on all 6 cores. Coupled with quad core RAM, and Titan Blacks in SLI, it was quite the PC.
Can you remember when the problem started?
Was it after you switched monitors, upgraded components, maybe a Windows update or upgrade?
Did you mention the make and model of your monitor?
