well I plan to have to seperate cooling loops I.E. one loop for each computer with a common radiator, namely the car rad.

I plan to have two inlets and two outlets on the rad one for each loop

I will run the loop from the radiator to the CPU block and then the GPU and northbridge.

In the P4 rig I will be using the dual outputs of the DD RBX block to got seperately to the GPU and NB then recombine them either using a y fitting or possibly with a third connection at the radiator directly.

the second computer will have a serial set of blocks CPU/GPU/NB then return to the radiator.

I am thinking two pumps should do the trick nicely I just need an idea of what GPH / Head of pump I should get for the loops. Obviously overkill is an option here as long as it doesnt cause things to burst due to overpressure.
