I have a Aqua computer cuplex pro on a Amd X2 4400 and a Nvidia 7800GTX Danger Den water block, Using 3/8 barb's and a Ehiem 1048 pump + a Duel 80mm Radiator. Just wondering if I should attach the Cpu water block and danger den water block to each other. Or should I make the cpu attach threw the radiator then the Video card, Or does it make no difference?.
