680 SLI First card runs hotter by 15C no matter which card is installed.
So at first I installed the Galaxy 4Gb card in first slot and the MSI 4Gb card in the second slot. Both cards run at the same freq but the Galaxy card was running 5C hotter at Idle and 12c Hotter at max load. So I ordered the Arctic Accelero Xtreme III. I installed it on the Galaxy card and put it back in Slot 1, no change. So because there was not much room for it to breathe in slot 1 I moved it to Slot 2. This of course is when I noticed it was slot related. Now the MSI card runs 15c hotter then the galaxy card in slot 2 at max load. I attached a pic of the setup. Not sure what would cause this. Anyone have any thoughts?
