I think the temp is a bit too high? since I want to train for about 2 hours, the fan is on 81%, I am wondering if it is better to set it to 90% or 100%? if it is necessary how to do it?

System info:
Up to date EndeavourOS with KDE/wayland, intel 11gen, Nvidia 3080Ti

I notice that diffusion_with_sdes/venv/bin/python is using a huge amount of memory this could be causing the higher temperatures. As far as the fan I am under the belief that it’s controlled by the temperature so I think it may be hardware programmed. However check for your specific card I could be wrong.

Yes it is, I am training a diffusion model. I see, you could be right, at least I didn’t find any command in nvidia-smi to directly control the fan

Nothing in nvidia-settings that i found either however check as i have a different card
