I have a fairly restrictive loop consisting of Socket2011 EK FN block, RIVE FN Blocks, SLI GTX 690's in series w/ FN Blocks, Aquaero WB, Mech Flow Meter (aquacomuter), Black ICE GTX 360 and 240 Rads.
I am using a dual pump, the MCP35x2 and achieving a flow rate around 1.5gpm
Without splitting the loop, I would like to increase flow rate by possibly adding another pump and was wondering what others thought about this endeavor or could adding a third pump actually be a detriment to my flowrate? Any advice would be appreciated.
If you currently are running 1.5gpm (assuming you are getting this from your flow meter...if it's accurate), you aren't gaining anything by adding another pump...the heat dump from the additional pump is going to offset the additional cooling potential by the slight increase of flow rate, so it's really a point of diminishing returns.
Otherwise, if you just have money you want to spend, it will work fine...won't cause any issues, but you aren't really going to see much benefit from adding it.
Thanks for helping to educate me Rubix. The watercooling bug has bit me full force and while my build may be overkill I am having fun learning as I go. I should of posted earlier my plans for expansion to 5 radiators hence the desire to run multiple pumps, still not sure if I would be better splitting the loop to two or going single. I plan on maximum overclocking of Sandy Bridge Extreme/ Ivy Bridge Extreme CPU.
I am still curious with the volume of rads and the pumps I have if I should go dual loop or single.
Full build is going in a Caselabs STH-10 I purchased consisting of:
(2) HW Labs Black Ice GTX 560
(1) HW Labs Black Ice GTX 480
(1) HW Labs Black Ice GTX 360
(1) HW Labs Black Ice GTX 240
