Do you need the stealth because of space restrictions? I was running 2 9800gx2's with blocks through a single GTX240 Rad on it's own loop with an mcp655. I am getting new blocks for my gtx295's, but I am not sure If I am going to add a 360mm rad at the bottom of my case to get temps lower.....You should be able to do it fine with some medium speed fans....
