I would assume the same logic would apply to dual pumps - pumping into inlet is better for flow/pressure than pumping into res chamber that feeds inlet.



Will certainly need testing, I agree. I see this as essentially being the same as running 2 pumps in series but having pump 1 dump water into a reservoir that feeds pump 2 - which is something nobody has really tested before because there hasn't been any reason to. As for benefits of series, don't the older EK Supreme's benefit a lot from the extra pressure?

Anyways Tim from Koolance, sorry for the derailing the thread slightly. I'm just very interested in these small details that are, from a max-OC/temp standpoint, largely inconsequential.
Sure, if you were looking to run dual/series for just the cpu block, two pumps in series will give you double pressure or about 30% more flow rate and a hair better temps with adequate rad.

I was just thinking in terms of a full cpu/gpu system..one big loop with pumps in series vs breaking it up into two loops but sharing the reservior will probaly give you roughly the same thing. Only difference is you could selectively balance or unbalance pumping power between parts. I would probably keep it separate and spoil the cpu with a pump to itself and just share the reservoirs.

Testing will sort out the performance questions..not sure.
