I have a few thousand cards that run around 70c all day long. That is nowhere near the thermal limit and they will run for a long long time like that. I wouldnt worry about temps at all until they are breaking 80c
Agreed. Below 80c is fine for almost every card. However, we've found that Vega's will throttle when HBM gets too hot - even in the 70's can sometimes impact performance. Crazy, but it happens with these finicky cards was all I was trying to point out.
