New concept for waterblock design: Heat Pipes

[migueld]

Water doesn't need as much surface area as air to work well... that's why we use it... and at some point the added surface area will just diminish the flow without any added cooling effect. This seems like a terribly inefficient way to use water in my opinion.

If that were true we would still be using the maze blocks . Why do you think blocks like the Apogee work so well with its pin matrix? More surface area.
