[WaterPimp]

I have done one better than that. i am running a 2 loop system also, but each loop has it's own rad & pump. I have the cpu loop running just the cpu block, and the gpu loop runs the gpu/chipset blocks. On the cpu loop i have a thermochill rad with 4 120mm fans on it and the gpu loop has a bix 2 with 4 fans on it. Both loops share a quad bay res. I have all of this in a full tower case that has been cut up to fit the rads. I had to move my 2 hdd up into the upper portion of the case and hung the bix 2 from the ceiling or the tower. the pumps are ehiem and a danner mag. my temps are lower than they have ever been. At full load I run 5.5 - 6 above ambient room temp.

system specs:

AMD 1700 @ 2405Ghz, vcore @ 1.95
1 gig pc 3200, fsb @ 200
custom RBX water block (cpu), DD maze 4 GPU (on 5900U)(btw 5900 oc'ed @ 575/1.1Ghz), and dd z-chip
