So I finally put my second 285 into my rig today and turned SLI on. Then when I check with realtemp, I found a huge temp delta between the two card. One of them idle at 38C while the other one is idel at 56c, I am sure the block were installed okay since I been using the old one (which is the higher temp one right now) for sometime now and it used to idle at 36c when on it's own.
It's this a normal thing to happen for SLI? Because one card is on 8X(higher temp) and the other one is on 16X? Why am I have a huge temp raise from single card?
Here is a pic for it, the lower card is the higher temp one, as you can see that both of the top card and the lower CPU(35C) has lower temp and the water block on the card does feel alot warmer, so the card is making alot more heat I assume? The tube on the top and bottom both feel cold.
