If you have a the 1st rev. of the card the volt reg's can be monitored via AtiTool, the top temp is the voltage reg temp. It can go 90C+ when you start oc'ing. This will put a low cieling on your OC. I zip-tied a 80mm fan directly on top of that area, only used two corners of the fan (use the little holes in video card itself). My v.r's never go above 60C now, if i were to OC more the cieling would now be due to physical limits of the cards memory or processor.
