Sup guys. Well I'm looking into doing a voltmod on my Sapphire x800gto2. It's already unlocked and oced to 540/591. My main question for you guys who already done this is: what kind of oc did you guys get after the mod and the temps with it? My biggest worry is temps. I do have a Artic Silencer on it also. Just recently with the hot weather I idle 36-38 and 50-55 load.
