Overclocking as much as I do, watercooling was a great thing for me. My PC is in an Antec DarkFleet and is silent with all fans on low speed. I watercooled for the low noise. The thing still heats up my room just as badly but at least I don't have to listen to it while it does it. Not to mention that watercooling just looks cool (side benefit ) The side effect is cost. It is definitely expensive to run a liquid setup I don't deny that at all. If you can get the temps under control using fans without it being too noisy I would go that route honestly.
