Liquid cooling (virgin)

[404 Error]

Hi guys! I'm looking to liquid cool my next custom build for overclocking purposes. Components used in the build are:

CPU: i7 4770K
GPUs: 2x MSI GTX 780 ti 3GB
Case: Phantom 630 (with window)
RAM: 32GB Corsair Dominator Platinum 2133
SSHDs: 2x 2TB Seagate Hyrbid SSHD
SSDs: 2x Samsung Evo 840 250GB
PSU: Corsair AX1200 Gold
DVD Drive: Pioneer 15x Blu Ray

(I thought I would give as much information about my build as possible).

I'm looking to watercool the CPU and both GPU's. Would I be correct in saying that two radiators are needed for a cooler flow? Or would you even go as far as three?

This is what I was thinking so far: http://www.pccasegear.com/index.php?main_page=wish_lists&wlcId=266733&action=wish_lists

If all that is compatible with eachother, can someone please suggest what tubing, fittings, coolant, etc. to use? Preferably referencing back to PCCG stock.

I'm still constantly reading watercooling guides but if someone could just double check my list and/or add to it, that would be appreciated! Any suggestions are welcomed.

For a CPU and 2 GPUs I would say a 360mm and a 240mm, both 60mm thick preferrably, is about the minimum rad space you need if you want quiet fans. I don't know how two 280mm radiators will compare to this, but I think they'd be fairly similar.

Get a premix for the coolant because it's less hassle. Something like Mayhems X1, EK premix, Feser etc.

I prefer compression fittings because I think they look nicer, and they feel more secure. Do you prefer these or barbs?

Tubing isn't too critical, just make sure you match the inner diameter (and outer, if you choose compression fittings) with the fittings. If you choose barbs get an inner diameter that is about 1/16" smaller than the barb so you get a really nice tight fit.

You have way overspecced on that PSU btw.

For that kind of setup, a 360 + 240 or 420 + 280 will suffice. 40mm + will do it.

Tubing is personal preference you might have to look around for what size you want but the 'done thing' is either 3/8 or 7/16 now really, 1/2 isn't really necessary and looks untidy in most rigs.

I currently use the EK XTX rads 1x 360 and 1x 240

Under benchmark loads the GPUs dont go over 40C and the CPU peaks at 59 with 4.2Ghz OC.

3 Radiators is not needed.

Of course the choice of fan also plays heavily on this. A word of warning though. If you decide to purchase Mayhem Pastel Coolant (which I am not a fan of) Check the tubing you use is compatible with the liquid as the wrong tube will cause the tubes to cloud within days.

Don't get mayhems pastel (is better advice)
