er, water cooling, why?

Why are most auto engines liquid-cooled? It's quieter and more efficient than air cooling. Same for PCs.
You get an OC'd PC with say four, five, even six fans going and it's going to sound like you've got a jet fighter in the room. A water cooling system only has a quiet coolant pump and a small fan on the radiator.
 
you mean a BIG fan on the radiator

the advantage is being able to use a larger fan than you could fit directly on your CPU or GPU due to room limitations

there's even huge free-standing heat sinks that look like those ionic breeze things, so that you can keep a pc cool with no fans at all.

You could even have the heat sink in another room, or outside, to keep the heat out of your room.
 
yes, fans can be quiet, but water can be silent

although without a good purging setup, you trade fan whirring for gurgling

most modern resevoirs are designed to minimize water noise, tho
 
Water cooling isn't really neccessary unless you overclock your processor or have overheating problems for other reasons. It does look cool and it is quieter than air cooling. Water is 100x more efficient at transferring heat than air is. My new system - haven't changed the signature yet - is air cooled using a thermaltake tower 12. I have the processor (C2E QX6800) overclocked to 3.3 ghz and the temp stayed at 45c for 24 hours @ 100% using JCS benchmark suite. (Although the back of my case is about 4 feet from my air conditioner) With a water-cooling system I could probably get the temperature down to within a few degrees of room temperature, but I don't think I need it.
