I just put up a watercooling solution, one reason being the noise. A LOT less noisy, but not noiseless.
If you want a really low-noise system, you'd have to watercool graphics card and possibly disks, too. That way you could get rid (almost) all of the fans, possibly only needing the (preferably adjustable) fan on PSU - and on radiator, if you use that type of watercooling.
