    im not sure if I am posting in the right area or not but im having some trouble and not sure why. When I start a game with both Gpu's in sli, Gpu1 jumps to like 70-80 degrees while gpu 2 doesn't move from 45. Literally soon as the loading screen finishes before I even play the gpu climbs up by like 30 degrees. Shouldn't they both come up together? and shouldn't they only get hot when under the load of the game, not the start menu?

    Are you sure SLI is enabled? It sounds like the game is only utilizing one GPU. Also, what system do you have?

    in the NVidia config it says SLI enabled. I had to reboot to get it to enable. im trying to play DayZ. when I play skyrim in SLI both of the gpu's come up in temp together and stay around 60 degrees with ultra settings. I have the new alienware 18

    The menu of the game could have activated the 3D state of the GPU's and, in the absence of vsync, resulted in full GPU utilization. There is no surprise that the GPU would get hot under such loads.

    The other GPU not rising in temperature is pretty much a sure sign that SLI is not running for this particular game. Maybe the game does not support SLI or maybe you don't have the latest driver that includes the necessary SLI profile for the game to utilize SLI. To convince yourself you can use MSI Afterburner or any kind of GPU monitoring tool to look at the utilization of the second GPU. There is not way a GPU can remain at idle temperatures while under load.
