I'm looking at a couple concepts I haven't seen tried yet on a PC.
The convection method requires the bottom of the water blcok to be at or slightly above the bottom of the radiator. The top of the the water block must be below the top of the radiator. As water is heated, it rises from the water block and returns to the top of the radiator. As is cools, it falls to the bottom of the radiator. The hot water rising draws cooler water from the bottom of the radiator into the bottom of the water block. The advantange of this system is that it requires no pump. If you don't think such a concept could work, find out how the Model T was cooled!
The other method requires me to use a coolant that boils at the temperature I want the CPU to operate at. It's the same physical arrangement as the convection system, but the coolant boils at a certain temp (say 40C), meaning that the CPU stays at that temp. The radiator is instead used as a condensor, where the evaporated coolant liquifies and returns to the bottom of the coolant block.
The main advantage of these systems is that they do not require pumps. Anyone with experience in this area is welcome to add comments or caveats to aid in my decision.
