I copied this from an answer of mine to an eariler question by Toolbox as it's easier that typing it all again:-
"Well I have the CLAP , and I got that to 82C once!, I think 60C is pretty normal, but it depends where you measure the temp.
I have a tower case and measure the temp from the top of the card on the PCB the otherside of the GPU. I tried various heatsink and fan combos including a 120mm fan on it, no kidding.
None of this really help alot as 40C was just about as low as it would go in non gaming use, I also have good case cooling (22C to 24C).
I finally solved it with an ICE 71 peltier @ 7v on an Alpha 3125 heatsink, now running at 18C to 24C in most situations, though it will go up to 32C with FSSAA enabled. This is total overkill I know, and I only tried it as I had the peltier and alpha sitting here. I will be water cooling it soon as I'd really like some PCI slots back
