    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.

    If I had to guess, the one that runs 20c more is your primary card. Is that card higher up than the other card, maybe restricted air flow? A picture of how the GPUs are set up in your PC would be nice.

    I have attached a few pictures of my setup in the case. There is nothing to restrict airflow at all. Both monitors are plugged into the top card.

    Is it the top card which is hotter than the bottom card? if so the top card is likely much warmer as heat rises (i know i'm stating the obvious here) and the airflow is pre-heated by the bottom card.

    You could try swapping the cards around and seeing if the card at the bottom in any hotter when at the top, that should hopefully help narrow the problem down.

    The case also looks pretty tight for airflow with all the hard drive bays at the front. Does it any any vents / fans on the side of the case?
