I recently built some watercooling for my q6600. Now i wonder which loop you think is the best.

Right now i´m using this loop

Pump-Radiator-Cpu-Gpu-Tank-Pump

Or is it better to go for

Pump-Cpu-Gpu-Radiator-Tank-Pump

My setup:
D-tek Fuzion with Quad Nozzle
Swiftech MCR220 ( Fans pulls air through radiator )
Swiftech Micro Res
Swiftech D5
EK RC600 Acetal Gpu
Everything is 1/2"

Maybe later i will install an singel radiator to the system. And is it better to let the fans blow through the radiator instead of pull ??

Hope someone can help me!
