I'm planning a dual-loop water-cooling setup. One loop for the CPU and one for the video card. Each would have its own radiator pump and block, but the lines would run from the radiator out to the block, to the inlet on the pump, then to a shared reservoir, each loop independent up to there. I'd like to have just one outflow line from the reservoir that branches in a Y fitting after 6-8 inches to then go to the inlets on each radiator. Basically two separate loops that share a reservoir and about 6 inches of line coming out of the reservoir.
Mechanically, I can't see any issues with this setup, as the pumps radiators and lines will be identical, but I know a lot of people here know more on this topic than I. Can anyone find anything wrong with this setup?
