Plus, all the heatpipe coolers have a liquid inside of them anyways...
The surface area of a radiator > any retail heatsink on the market right now. It's a combined effort. The water has a higher heat capacity, a higher thermal conductivity, and it's able to transfer the heat to a separate device that dissipates the heat more efficiently than any heatpipe/heatsink. Sure, air pushes the dissipated heat from the system, but the air pulling cold air into the radiator is more important. The radiator evaporates the heat through its fins and then colder water circulates back into the system.
Regardless, everyone posting in this thread about air did nothing but theorize and argue without facts.
The best water is no longer $600+. You could get the best water for a full CPU/GPU loop for less than $350. Anywhere from $180-300, you could have a water cooling system that takes your system to a new level of frequencies. Of course it has its cons, but it wouldn't be as popular as it is, if air offered the "same performance".
