Description
NVIDIA Open GPU Kernel Modules Version
515.48.07-3
Does this happen with the proprietary driver (of the same version) as well?
No
Operating System and Version
Arch Linux
Kernel Release
5.18.2-arch1-1
Hardware: GPU
GTX 1660ti
Describe the bug
When using the opensource drivers, the system reports considerably higher gpu temps than the closed source ones. The closed source driver idles around 40C while the opensource one idles around 46C and this increases when doing higher-demanding tasks.
To Reproduce
- Install nvidia-open drivers
- Run these drivers
- Check output of nvidia-smi(or any other temperature application).

Research direction
Start by reviewing the attached nvidia-bug-report.log.gz and reproducing the comparison on Arch Linux with kernel 5.18.2-arch1-1, using nvidia-smi to measure idle and higher-demanding temperatures for the open and proprietary drivers. Done means identifying and resolving the temperature difference, with measurements showing comparable behavior.
