I thought of another idea!!!

Yep, im back with yet another idea.

This time is a dual pump concept. basically you have a single res and you have two pumps taking coolant from it. One pump goes to my gpu waterblock, and another to the cpu. The idea would be less distance for the water to flow, and less pressure. Also it should even out the coolant temp. Only other thing i could think of is adding a third pump, which goes to just radiators, thus the coolant is being drawn from the res as well, and then being just cooled. Oh, and anotehr idea that comes into my mind. a Split res, oh heck, i will explain this later on. Anywayz, replies will be nice

from what i know, the tightest restriction in the system, the system headheight, and the pump used, determines the flow rate. so if the gpu block has less restriction than the cpu block, the flow rate through the gpu block will be higher than the flow rate in the cpu block. this assumes both pumps are the same. if the gpu block is just as restrictive as the cpu block, then both flow rates will be the same, so there would be no benefit in running two pumps in that situation.

id say instead of spending the money on two pumps, just buy a more powerful single pump and a bigger radiator or two or reserators if u want silence.

Ya the thing is when you try and run both of them back together into radiator, your gonna have to use like a y splitter and then your trying to force twice the water or coolant into the same area so your pressure is gonna increase and your flow rate most likely will drop. I doubt it would be any more effective. Mvgustas suggestion is a good one though, a bigger pump and a bigger radiator should help you out.

But I don't know much about WC so that is just my take from a physics point of view.

thanks for the replies. i was thinking about the water flow today, and you could just get converters, so once the 3.8" tubing of mine gets past the blocks, they convert to 1/2" before going into a 1/2" y split. Also the rad would have to be fitted with 1/2" etc, but that would lower the pressure drop, and thus quicker flow.

Ya that would help with the water flow problem, could work, don't know how much it would help your cooling though, probably wouldn't affect the cpu at all but could drop your gpu temps since you aren't running already heated water over the block.
