Re: Have I fried my 580?
With my old rig I had the nvidia drivers set up with a fan profile that sped up the fan to 100% under heavy load, and the cards will still get into the mid 90s (97c being the highest I ever saw, and I saw it frequently). I was hoping to avoid that with my new case. Anyway, I did the same thing (using EVGA Precision this time) with the fans running 70% when the temp gets to the 70c range (60% for 60c, 80% for 80c, and 100% for 90c), and the cards both stayed in the mid-70s C runnig the Uniengine Heaven demo for two hours straight with no issue. At least the fans aren't 100% any more.
I'll have to do some more testing with Crysis 2 and other games to confirm, but it looks if the cards stay below 80c then they'll function properly. That also indicates to me that I probably did some damage to the cards with my old setup (I love it: the new case has half the fans but far better airflow - CM Stackers suck).
