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.
I had a similar issue with my 3 card setup some fans sorted it. It was the card that had the most space that was the hottest. It was almost near the CPU though. The squashed card was the coolest as it had the hotest card sucking heat off it and going onto itself.
Yes you will want risers.
My cards were not blower style and I couldn't get the hotest card above 70% tpd or it would go oever 70C.
I think your right. Recommendation on where to get a powered riser? I have (2) of the old school ribbon ones.. can I use those?
