SLI Cooling

Hi guys, what sort of cooling options are available for GTX 260 SLI. I'm planning on getting the Lian Li X2000 but despite this I don't think I'll be happy with the ~55db fan volume on the 260s. I don't know whether I'll be able to get away with just aftermarket air cooling as I'm planning on chucking an X-Fi sound card onto the motherboard and I can't imagine all these things stacking up.

I think I would prefer air cooling but as I said, not sure if it is even possible. Not quite sure I could live with air cooling at all as even in the X2000, the video cards are at the bottom in a poorly ventilated area so it's going to get quite cramped and hot with all these things in place. If I go water cooling, I think I will probably have one system that cools both GPUs and the CPU but I would prefer to contain the whole system within the case.

Any ideas?

P.S. I know nothing about water cooling so I don't even know whether I'll be able to get away with a totally internally contained cooling solution or whether I'll need some massive radiators that will have to be placed on the outside of the case which is a massively undesirable solution for me.

Modify this post and redo it in the watercooling section if you need watercooling help. At the top of that subforum is some great faqs etc too.

Honestly in SLI config the heat isnt a huge issue, you can set a minumum fan profile of 60% which is barely audible and set the max to 100% using rivatuner. When i ran 2 cards i had no heat issues, with 3 i have to manually set the profile to 80% all the time for gaming or folding.
