I have a GeForce 9800GT. Is it true you can buy after market coolers? Because my GPU is hitting 65Cish, when idling. So.........Any help?
That's normal, some cards idle at 83C, which is again, normal. There's no need to buy an aftermarket cooler unless either it's too noisy, or you get graphical corruption/crashes.
I disadvise this for a reason, I destroyed one of my cards trying to fit an aftermarket cooler (Arctic Accelero S1 rev 2) as per the instructions. Better coolers such as the HR-03s (which I have installed successfully in the past) work fine, but aren't cheap. Unless you're after quietness, there's no reason to get one.
