Custom water loop for high end pc

Hey guys, just a quick question I need to ask. I'm thinking about building a high end PC (I'm going all out on the parts by the way) and I'm thinking about buying a custom water loop. I want to overclock my gpu and cpu pretty damn high, and I want your opinion on my theoretical water loop:

-2x 480mm radiator (top and bottom), 360mm radiator (front), blocks and reservoir (below)

Now this loop is going to be in my Corsair 900D case, and it's going to be cooling the following parts:

-Intel core i7 4960k
-4-way SLI EVGA GTX 780 TI
-Lepa G-series 1600w PSU
-----------------------------------------
11x Noctua NF-F12

I have other parts obviously, but these are the parts that truly matter with water cooling. If you could evaluate it and see how high I can overclock my gpu and cpu with this, or swap out some parts of the loop to get the most of my overclocking experience that would be much appreciated. Thanks for giving me some of your time!

EDIT:I never decided on the brand for any of my loop parts, so brand names would help as well. ;)

for best results on your water loop run 2 different loops for the cpu and gpus. You can also get way with a 480 for the gpus and a 360 on the cpu running push/pull on the rads. If your wanting to run all 3 rads and in one loop look into running 2 or 3 pumps in series to help push though all the blocks and rads.

For overclocking not all electrical components are created equal so no one can really tell you how high they will go, it also depends on how much your willing to risk your hardware get that little extra out of it. Remember you have to pay to play and if you push to hard it will cost you.


Also to help you out make sure you look for waterblocks for the 780's before you buy the card, sometimes this will persuade you to get a different brand or model of card since a lot of times they only make blocks for reference cards.

In what universe are you ever going to need a 480mm radiator in push pull to cool a cpu? That's just way too much radiator. You can't cool below ambient temperature no matter how many radiators you have, for the gpu's in a separate loop yes I can definitely see that being useful with 4 of those cards but they typically should dissipate around 1300w of heat with just 4 normal fans. So your 4 cards should put out at max 1000w of heat plus your cpu which is under 100w you're really REALLY REAAAAAALLY over killing what you need since one 480mm rad is enough.

If you read my post you would see that I said to run a 360 rad for the cpu. Standard cooling for a cpu is a 240mm radiator, since he's running a i7 4960k they already run warm and with overclocking a 360mm radiator will do just fine. As for push pull fans on the radiator it just a standard practice for me to run all my rad's like that, yes you don't have to do it that way but is the best way to cool the radiator down.
