All temps for cpu are the single highest core temp - 1 of the cores is consistently 5-6c hotter than the others. Max gpu temp is the single hottest card from the test.

I literally just finished this testing and posted it moments ago in my build log. This is using the 580 EK black acetal - NE water-blocks, EK backplates, EK dual pump-top (D5s in serial), 2 XSPC 360 rads, EK res, yada yada. I don't know much of anything about the koolance blocks but I can at least offer some raw data of a system that just went up Nov 26 and probably still has plenty of bubbles in it yet to be cleared.
