i wana do the water cooling part of clocking now and all i wana know is if i use a pump that pumps 750 lph will it be ok if i put three radiators and i Reservoir on it and a cpu block and two gpu blocks will it be ok to pump throw all that in a full tower with the pump being on the top of the case and the Reservoir on the bottom??????? i will be using these conponents:XSPC X2O 750 Dual 5.25” Bay Reservoir Pump,XSPC AX360 Triple Fan Radiator ,2xXSPC AX240 Dual Fan Radiator (Black),ICS Extreme Flange Reservoir - Black with a Silver Kill Coil in it,2xZalman ZM-GWB8800 GTS VGA Waterblock,XSPC RayStorm CPU WaterBlock (Intel),and there will be dhark fans on the radiators..
You do realize that the pump you listed is already contained within a reservoir. You can have two but there isn't really a need for two.
Why don't you get slightly cheaper rads and get a better pump with the savings?
FYI, you can calculate if any pump will be sufficient for a planned loop, it's all about calculating flow restriction. It's best to do the calculations yourself rather than blindly trust someones answer.
