Actually I have been thinking of how to encoorperate a heatpipe/watercooled block for some time now. The main problem is that heatpipes work best (again) when the difference between the hot side and the cold side is greater.

Heat pipes are simply sealed tubes with some sort of liquid sealed inside in a vacuum. The tubes are not filled completely on purpose as well. When one side of the heat pipe gets hot, it evaporates the liquid and moves the heat to the top or other side of the heatpipe (which is naturally cooler) where it condenses back into a liquid again.

What we would have to do is locate a liquid that boils at a lower temperature than what most heatpipes are made to boil at and then keep the temp lower with our water setups.

For example, I believe that the new Shuttle Mini cases use H20 heatpipes to keep the P4s cool. Well H20 in a vacuum will probably begin to boil off at about 47C. What we would need is a liqid that would boil off at say 20-25C and then our watercooling setups would need to keep the hot side at about 30-32C.

Correct my numbers or thoughts if necessary but I believe that is the way to go in order to be able to use a good heatpipe setup with watercooling.
