Mine was the hydro copper version, so under load it never went above 40C. Overclocked really great, but, couldn't get all three monitors to run surround - which is what I bought it for in the first place
First card gave me one clear monitor w/ the other two displaying horizontal green lines from anything painted on the screen. RMA card gave me two clear monitors with green horizontal lines from any painted image.
Decided two out of two was about my limit so I'm returning them for a full refund.
A shame cause it's a beautiful card and did OC fairly well. Since gaming is really the only thing it's good for, why keep it. Had I only had 1 monitor to hook it up to I'd have been fat dumb and happy with either card, but.......
