Hi all, I'm currently building a new desktop and I'll be going down the watercooling route. I currently have a i7 3930K what i would probably OC to around 4.5Ghz and I will be buying 2 'GTX780s' when they are released.

Would a single 320mm x 60mm radiator be enough to cool it down or would I need to add in a second 240mm radiator?

The reason i ask this is because I have Corsair 800D case and I want to avoid modding it as I don't want to cut it up but it's looking like that is what I might have to do

You're asking about cooling products that have not been released, in a case which we have not seen the inside of, with unknown models of radiators.

How about get it installed, see how it works, and then if you need the extra cooling...do that.

Sorry, I'll be more specific...

The 320mm radiator is a XSPC RX360 and the 240mm is a EK-Coolstream Rad XT. I will be using Corsair SP120 high pressure fans 62.74CFM.

The case is an 800D so I have a fair amount of room inside of it but I haven't started putting anything else in it yet (Asus Rampage IV Extreme & Corsair AX1200i PSU and the 3930K are all still in their boxes unfortunately :( )

Also going with an Alphacool 655 pump, if that changes anything?

I was originally planning to get a single Titan but now with rumours the 780 may be out soon I think I might as well go for two of those, I did want to avoid SLI again really but I can't say no to the added performance!

So while it is vague for me to ask as we don't know the temperatures of the cards but I was just wondering what others use for a system with 2 GPU's and 1 CPU

Hope this is a bit clearer

I have liquid cooled 2 gpus and a cpu. though I went way overkill on my system ( i am a member on ocn where overkill is the norm)

I am cooling my sig rig i7 930 @ 4.5ghz and both 5870's with an rx 480 and an rx240 in my 800D. load temps never go over 66C for cpu and 38C gpu

( and I use a swiftech 655 vario ( basically the same pump as your alphacool but variable ) I hope this helps..
