I think default fan speed on this thing is only 20% but even at that it doesn't go a hair over 80c full load. It idles around 60c. It could be better but is in a very safe range I believe. I would fully recommend this card. I have an old 4200 X2 AMD processor and 2 gigs of old 400 ram and I can still run Crysis fluidly on max settings. This was also when I still had a 8mb cache ata 100 hard drive which I just upgraded.
