Theres a big difference, a HSF picks up the heat and dissipates it with air. Wc'ing picks up the heat with water and then dissipates it with air.
Water has a lot better specific heat capabilities, it picks up heat much better then any common material, then it's moved to a remote location where the heat is dissipated by air, the rad has so much more surface area then a HSF that any inefficiencies are more of less negated.
A HSF is completely dependent on air for heat pick up and dissipation. Air has a lousy specific heat index, air is an insulator. Even a heat pipe that picks up heat when the liquid turns to gas, then it travels up to the fins where it's condensed back into a liquid and goes back to the base of the HSF. It's a continual cycle.
Someday heat pipe technology may very well rival water, but it doesn't now.
Thats for common gear like we use, I'm sure a heat pipe type HSF could be made that would rival water. But then any carbon or diamond type technology that could be used for heat pipes could also be used on WC'ing also.Edited by ira-k - 2/20/10 at 8:19pm
