What deters me from putting everything on just one loop is the amount of heat the vc loop puts out. I am running 2 x EVGA 285 FTW's, I run 24/7 at factory clock of 720, when benching have had them over 800. If I am in a gaming mood and play all day they can easily reach 60 degrees +.

Room temps can get into low 80's when hubby's machine is on also, so I have to look at getting maximum cooling.

Having already got 2 x D5's cost wise the T3 is definately the way to go! Guess best way is to buy one and just see how it goes in various different configurations.

If I do combine both loops, has anyone tried with different diameter tubes? One loop is 1/2 and the other 3/8.
