Thinking of water cooling

[Crash]

Is it a good idea and what are people using?

I got a set, on the CPU. Closed circuit. Plus side besides good cooling, is less noise!

Corsair Hydro H55:

I've also got a Corsair liquid cooling CPU setup - the Hydro H75 from memory - I wasn't happy with the performance of the 2 fans it shipped with (v. noisy) so I swapped them out for a pair of Alpenföhn fans which, while not cheap (about £20 each) are the quietest fans I've ever found for the PC. When the machine is not being pushed, it is completely silent unless you're right by the case (and even then I think that's due to the GPU fans) and even when in a game the noise level is still very acceptable. CPU temperatures are typically about 10 degC above ambient when idling and I've never seen them reach 60 degC under load. All in all, I like it a lot.
