linux gpu usage compared to windows

my gpu rn is at a stable 33 degrees celsius with fans turned off and pc has been turned on for about 6 hours. on windows after 1 hour the gpu gets to 50 degrees and I have to keep the fans at 25% to keep it constanstly under 30 degrees. gpu usage is very low tho about 3, 4% and I dont use any gpu intensive software. any idea why? anybody else experiences it? nvidia gpu btw
