Building water cooling system for 2 GTX 480, any advice?

Solution
Likely, but it depends on what fans you get for the rad you choose. You will either be right at threshold, or have some wiggle room depending on your rad/fan choice. In most cases, my rule of thumb is minimum 1 CPU or GPU per 2x120 radiator surface area.

Are you running a single loop, or separate loops for CPU/GPUs?
@OP:

Are you planning to upgrade your GPU's at any point? If so, you might consider a universal block like the MCW80 and using RAMsinks for the RAM modules. A full cover block will work fine, but is more costly and won't work on the next series of card (ex. GTX580, etc) For the cost of 1 full cover block, you could almost get 2 MCW80's and the RAMsinks needed to complete that option.

You could also consider the Swiftech full cover 'plates' that go with the MCW80 block. Between the block and plate, you'd pay almost as much as a full cover block, but you can reuse the block and just get a different plate for the next series of card... buy another $45 'plate', or buy another $130 full cover block.

But, if you don't mind the price, full blocks are great; just do some research before you buy...not all perform the same.
 
 



RES-PUMP-RADIATOR-2ND GPU-1ST GPU- RES is it fine?
 



i agree, but MCW80 and using RAMsinks is not good fore SLI, IT WILL BE NOT SO EASY TO BEND 1/2 . am i right? and i will wait for 580 card, and I also read that NVDIA will release new cards after new year.
 
I run SLI GTX260's with MCW60 blocks and RAMsinks. It would be almost the exact same setup as I described for you, just different block models (the MCW80 is the newer version). Where do you get your info?

Yes. It is very possible to bend if you get tubing with good flex properties, such as Tygon or Feser...there are others as well.

i will run separate loop one is for CPU triple rad and one fore 2 gtx 480 quad rad
