Your GPU goes over 80C at only 70-80% utilization? And at 90-95% utilization it reaches 90C? Dude, there is something wrong with your card. Try to replace thermal paste. Or try to set fan curve more aggressively. I have RTX 3090 and even in the middle of the summer when there is more than 30C in my room, my GPU temps never go above 75C at full 100% utilization.
