What gpu is it? What you really want to pay attention to is the hot spot temp. Which is usually 10 c higher than the GPU temp. What you are trying to do is find the right balance between temps and fan noise levels. so on mine I have it set to 0-50c =0% fan speed. Then when it hits 50c it kicks in about 44%. And that way it remains fairly quiet and fairly cool.
Wait just reread your post and realised you posted before saying you had a 4070ti super. Have you tried power limiting your card to like 80-90% you wont lose a great deal of performance.
if you do nothing that was said in this post you off to a good start
