I was thinking about the loop that you have, and was thinking' what if you had it set up like this?: resi-240rad-video cards-360rad-cpu- back to resi? I know it would kind of mess up your color scheme you got going on, but it seems like your transferring the heat from the cards to the cpu and then cooling off the water twice for the cards again... I dont know, it was just a thought.
the colors are legit though. I really dig it.
