Piggybacking on this… do all nvidia cards have the same issue with Linux drivers, where the fan won’t ever go below 30%? I have a 3090 on Ubuntu 24 and hours of googling netted nothing that worked.
FWIW - the fans on my 4070ti super turn off during idle in pop, bazzite, and cachy (just like on windows). Definitely no being stuck at 30% that I’ve experienced
