I have 3 1080ti's on one board

Running into an unusual heat from my first card.. it hits 75/85 where the other 2 are holding around 60..

Running at 70 tdp with 70% fan speed.. been stable for a while now. It's hot in the basement, but temps were stable until now..

Need to get some risers.. I used to have some, cant figire out where they went.
