But but but...and look what happened. You shouldn't have to run your fan that high to get those temps in the first place. Even with 100% fan those temps are way too high. I can run 6950's at 40% fan temps in the mid 60's. It is all about having good airflow with the proper case.

How did you manage to cool them that well?

What case and fans do you use? Their placement?

Please tell all the details.

1.3v on air ? you're brave. That sort of voltage should be use when watercooling imo.

Also I disagree with the point that a manuf. considers it abuse to run a fan at 100% 24/7. Fans have tens of thousands of hours MTBF. Running fans full speed, for a long long time might wear out the bearings....but I don't consider this abuse - running the poor card @ 1.3v under full load is.

For a few hours benchmarks its fine, but 24/7 no card is going to last long at that voltage with the stock HSF

Try telling that to new miners who never built a system before, or might've just been casually gaming at most.

It doesn't matter if your core temp shows 70-80c in afterburner.

The card *will* die with that voltage in a few months, maybe even weeks. And there are examples on the forum if you have the motivation to search for these 2-week-wonders.
