Two Loops, One radiator

[bluehaze]

Did you forget your pump? Keep it simple, res-pump- then whatever routing gives you the shortest runs of tubing.

Pumps are mounted on the res with Typhoon III.

I guess this would work, it seems a less than optimal solution though as far as flow rates are concerned. You will have a really high flow rate through radiator and a really low flowrate through all the blocks which is exactly opposite of what you want. To an extent higher flow through blocks = lower temps, and lower flow through rad = lower temps.

It will be interesting to see though if you hookup a controller to each of the pumps the tuning options could make a significant difference finding optimal flow rate through the rad and optimal flow rate through the blocks seperately as long as you could get a decent flow through the blocks with just the one pump.

Edit: Giving it a second thought I'm not sure how well it would work with that particular res though because the inlet of the res is so close to the inlet of the pumps that the temps of water flowing through rad and water flowing through blocks on 2 seperate loops might never equalize or at least take an extremely long time to equalize which with the rad on a seperate loop would be really bad.
