I am designing my watercooling setup, and I have come to a bit of an impasse. The setup will include a dual opteron setup on a Tyan K8WE motherboard. I will eventually be upgrading to a dual nvidia 7800 setup.
Here is the situation: I have opted for the swiftech storm waterblock for both the CPUs. Each storm waterblock has a head loss of ~6.3 ft. I want to set this up as a parallel cooling system. Each storm waterblock will be on its own fluid circuit, and the gpu waterblocks and chipset waterblocks on the final fluid circuit (in serial). After doing a preliminary workthrough, it seems that the 2 gpu waterblocks and 3 chipset waterblocks (alone) do not come near a head loss of 6.3 ft. Nevertheless, the additional tubing and additional bends required to set up the serial circuit will probably bring the head loss near equivalent to (or over) what I need (I want flow to the CPUs to be greatest). I am looking at running 2.5-3 gpm for each circuit, or a total of 7.5-9 gpm. I was wondering what you all suggested for GPU and Chipset waterblocks at this flow rate? The ones I was looking at were the Silverprop Nexus and Fusion waterblocks because they had excellent C/W ratings at 2.5-3 gpm. I was looking at the Swiftech MCW55, but I haven't been able to find the C/W ratings nor the pressure drop. What d'ya think?
