The bottleneck causing your low flow rate is the pressure drop of all of those restrictive blocks you have for motherboard cooling.
Parallel pumps won't give you significantly more flow against a restriction than a single pump because their head pressure doesn't add in a parallel configuration.
You have a very restrictive loop, so you need more available head pressure to force the water through it.
You need SERIES pumps to increase the available head pressure to force more flow through a restrictive loop because their head pressure adds in a series configuration.Edited by Caleal - 4/25/11 at 12:59pm
