I have two GTX680's with XSPC full waterblocks and the water connecting bridges setup for parallel. The top card runs @ about 10 C higher than the bottom card. @ load the top card runs about 60 C and the bottom card runs @ about 50 C. Now, I do see that in GPUZ the top card also shows the idle power consumption @ 11.4 % TDP Vs the lower card @ 10.5 % TDP. Could this be the reason for that much of a temperature difference, does one card utilize more power in SLI, or is something else going on or is this normal?
