I am planning on watercooling my tri-sli 480gtx evga set up. This will be my first watercooling experience so i could do with some advice.

Firstly equipment. I realise these gpus will be putting out quite a bit of heat so i was thinking of going for an external Phobya extreme nova 1040 radiator. This takes 9 fans so i think it should be enough. I was going to go for ek full cover blocks - do i need back plates as well? Do these blocks come with barbs? Also how do i connect the three cards together? Is this what linking blocks are for? Detailed instructions on this would be appreciated.

Would a single good pump be enough for this considering all the tubing going to the external rad? I was looking at the Alphacool laing D5. Is a top needed?

Any tips and advice will be greatly appreciated.
 
You don't need back plates. They're nice to have in terms of giving your card structural support and slightly better cooling, but it's not necessary.

Linking GPU's is as easy as getting connectors, just look up SLI connectors. Or, you can get this, which would look much nicer: EK Bridge link. I recommend the parallel flow design for your setup.

They usually come with barbs.

A 480 radiator would probably suffice for your setup, but won't be whisper quiet when under load. Just some moderate noise, but nothing loud.

If you're going big and external, get the Mo-Ra Pro 3 140mm fan version.

I would go with two D5's in serial. No need for a custom top unless you want a version that looks nicer or has the reservoir attached.

One thing almost all new watercoolers forget: DON'T FORGET THE SILVER KILLCOIL OR PT NUKE.
 
I ran a 480 and a i7 860 heavily OC on a XSPC RS360. My video card hanged around 55c at max load and my CPU would get to 80c sometimes if I recall. Just something to measure against I guess.
 
I really want to watercool my 470's but dont want to regret paying for the waterblocks for a two, soon to be three generation old video card. Please let us know how this turns out, maybe you will talk me into it :p

I wouldn't either, even on my 570's
