Ask the Doctor: Feelin' My Flow

After many years of heating my room with an air-cooled PC, I’m thinking about building a water-cooled system. Since most rigs have blocks for just a CPU and maybe two videocards, I need some advice on how much pressure the pump needs to put out. My liquid circuit will include blocks for a Phenom 9950, two videocards, and some OCZ Flex IIs (liquid-cooled RAM). I’m worried about flow restriction from the length of the liquid circuit and the cooling effectiveness for the RAM. —Michael O. Click for Michael's answer, after the jump! read more (link)
