Thermal Shutdown using PRIME

Hello, I am currently having an issue with my dell laptop where anytime I run a load with prime-run my system doesn’t seem to thermal throttle properly. The nvidia xserver settings reports slowdown temp (which I am assuming is thermal throttle?) of 96 degrees however my system shuts down at 93-94. I also had this problem on the unstable debian branch (debian 11 IIRC) but have been using manjaro for a while and figured I’d actually ask for help this time.

It’s not an issue with cooling in general as in windows it can throttle and manage it’s self just fine, Running sensors in linux I can see and feel the fans doing work. I’m also assuming it’s not driver related as I’m gone through several driver updates/reinstalls and no one else is having this issue (as far as I can find).

The system shuts down when the CPU or ISA bus gets to that T°, not the GPU.

I disagree: Windows throttles differently.

So it’s time to vacuum that baby or better: buy a can of compressed air and blow compressed air in all vents and openings (SD card reader, USB ports, …)

If it still happens, we’ll need some T* monitoring going on,

That’s EOL, so upgrade to 5.4 LTS or 5.10 (LTS candidate)
