First Build, Help on watercooling.

I'm pretty much completely new to building computers but I've done a lot of research on the subject recently and have been able to pick out most of my parts. I plan to go with the new Intel 4770k cpu which I will overclock and for my motherboard I will go with the Asus RoG Maximus VI Formula once it comes out. For my GPU I plan to go with dual EVGA GeForce GTX 780 Hydro Copper and for my case I plan to go with the NZXT 530 when it comes out or possibly the 630. Where I'm getting hung up on is how many radiators I need as well as the pump I should use. I've tried reading the watercooling sticky here and many other guides on other sites but I have yet to see a real clear example of how many radiators I should have. I remember reading or hearing somewhere that its good to have at least 1 more radiator then you do waterblocks so I am assuming that I will need a triple radiator and a dual radiator in order to cool both my GPUs, my CPU, and the VRM cooling block that comes with my motherboard. I am also assuming that a good pump for this setup would be a D5 pump. I would just like to make sure that this is what I need. I'm not worried about cost I just don't want to go overboard.

edit: As I am new to watercooling I would like to go with a kit. Could someone give me suggestions for a kit that might work for this setup? I've looked into getting a kit from EK as well as from XZPC but I don't know if either kit's pump would be able to handle my future setup.

You are right and nice to see someone reading for one rather than just askung for a parts list lol

A 360 and 240 would work, but suggest 2 360 if you have room.the EK kits use a Jingway pump, and not much review data is out there for them. I'd stick with a D5 variant. XSPC makes kits with D5 pumps instead of the crappy x20. A D5 360 kit, extra 360, extra tubing, fittings, and gpu blocks would suit you nicely. On mobile or I'd link em lol. Performance pcs carries the d5 versions

For dual 780's (correct?) and a 4670k, that's about 600W to deal with before overclocking.
Look up reviews on radiators (Martins Liquid Lab and Skinee's Lab are good sites for this) and see how much they can cool at reasonable fan RPM values (~1000 is good). From there pick your radiator setup.

Since you are going to be cooling dual cards, thats going to add a lot of restriction to the loop. You should look at putting the cards in parallel to lower their flow restriction.

I started with an XSPC kit, and their the brand I am most knowledgeable in so I recommend you get one of their D5 Raystorm kits and then add on the radiator space you need.
Or build a loop from the ground up.

Plus the mobo vrm block so what... 12 phase dual stack I think on that mobo - 70-90w tdp? Ish? So plan for 675-700 capacity. Meh a fair 360 and 240 could do it

I doubt the mobo VRM's are going to be kicking out 125W. If we could cool that kind of heat output with mostly passive and relatively small heatsinks found on mobo VRM's, makes the purpose of fans on heatsinks kind of pointless.

Would expect maybe 40W at most, and that's with pretty heavy overclocking.

Thank you manofchalk. You are correct in the dual 780s I was considering going a parallel loop mainly because that's loop that I know as well as the fact that it is less restriction. I looked at the XSPC kit and I find that I don't particularly like the bay reservoir/pump combo so I will most likely build my loop from the group upn using a swiftech 655 pump. I still haven't chosen a reservoir though I do know I would like to go with a cylinder shaped reservoir instead of a box or bay reservoir, I just prefer the way it'll look. Also since I don't plan to do heavy over clocking and most mobos can get away with passive cooling on the vrms so I figured it shouldn't put out a tremendous amount of heat so I should be able to get away with a high quality 360 and 240 rad.

Thanks Buzz. I wanted a second opinion to make sure about what I was going to do before i started buying components.

risaaccess, Ive watched all of those videos at least 2 times if not more, its one of the reasons that I plan on going with water cooling and its shown me how I need to set up loops.

Thought I previously, but apparently I didn't lol

Will do, just not going to be for a while, have to wait for motherboard to come out and much more lol
