Hello,
I am looking for opinions about building a dedicated loop for my system.
My current specs are an older AMD fx cpu, and a cheap ASrock motherboard. However, this will mainly be ran using either an Ivy-bridge or Haswell i5 and either a sabertooth or ROG motherboard. I am running one EVGA gtx 770 but plan to add a second one down the line. My case Is a Rosewill Black-Hawk Ultra.

Before I move onto a major CPU and motherboard upgrade, I am biding my time building a water-cooling loop. I currently have a corsair H100 installed. I would like opinions on if I should leave the H100 in place, and build my loop GPU specific, or ditch the H100 and add my cpu into the loop. So far I am planning to use a Swiftech D5 pump variant and an XSPC res with the pump top built in. I am planning to overclock the cpu and gpu to some extent and am curious how much/many radiator I will be needing. Any input welcome

Firstly, good rule of thumb is 240mm of radiator space for a cpu and 120 for everything after that. I'd start with it being gpu specific, and then you can just expand it when the h100 stops cutting it. Hope I helped ;)

GPU typically has higher TDP than CPU, so you'd want to allocate more radiator space per GPU than simply your CPU. Of course, when you overclock, your TDP rises exponentially (see watercooling sticky for how to calculate CPU TDP @ overclock) and apply accordingly to your overall loop TDP cooling needs.

Thanks for the info! Dependently on what radiators I choose I may leave the H100 in place for awhile. Not much resale value and I hate to throw it in the parts bin. My case is huge so I have plenty of space

Sorry, my mistake. I thought I put GPU instead, but clearly not.

No worries; I think many people prioritize CPU as putting out more heat in watts over a mainstream or flagship GPU, but in almost every case the GPU has a higher TDP.
