Hmmm, interesting. Then I guess ill stick with single loop. But I think I'm gonna get a second pump, run them togethar. Space isn't really an issue though, I don't plan on haveing more than 5 drives anyway. (4x2tb greens in hot swap bays, 60gb ssd hidden in back of case) so I'm still gonna fit a dual rad in the bottom of case. And as for the pumps/res, I was gonna use a dual pump, dual loop xspc double 5 1/4 bay res so pumps and res's are completely cleaned up.

Btw how much heat does a x58 board put out total between the chipsets and vrm's? 50w?
