Let me get the obvious out of the way:
- There is no dust, I took apart the laptop and cleaned everything out.
- I re-applied thermal paste on the GPU (after this issue began not before)
- The laptop is elevated sufficiently, all vents are open to air and no obstructions
This is a new issue, it has not done this for a year.
Additional info: Windows 11, additional SSD installed (the day I got it)
Does anyone have any ideas?
