I have recently spent quite a lot of money on upgrading my computer so it would incorporate SLI. I have 2 550TI cards at the moment which are identical. The problem that I am having is that one of them is running nearly 20c hotter than the other. 57c at idle and on load well over 80c. I was after some advise whether there is some specific SLI cooling I could purchase or a way to cool it down. I have tried under clocking the card and it doesn't seem to effect the temp by more than 2c. I have attached a picture of the temps of both cards at idol.
