i raise the volts a little on the 560ti (not sure exactly) but i still idle 35-40c and hit 75c under 100% use n it doesnt go any higher. do you think that would affect the 560ti at all?
That should be fine. They can technically cope with temps up to around 100-105c, though that would wear the card out real quick. I personally try not to go too close to 90c in stress tests (Furmark etc); in games it'll never quite get as hot.
