It is a very special day in every serious overclocker's career when they are able to take the big leap into the world of phase change (also called "vapor compression") cooling. For those who are unfamiliar with phase change, it is essentially the same concept as an air conditioning or refrigeration system, except that a refrigerant is evaporated in a small block mounted directly on the CPU. What this equates to is the ability to maintain extremely cold temperatures on a processor, even under load.
