So we ended up putting in two 60mm fans, and we came up with a water-cooled heat sink as well for the CPU. We've actually applied for a patent on that one. He goes on to decribe a setup where water under reduced pressure boils in the hot part, and condenses in the fins. Two questions: Can such an old invention really be patented, and what happens when you stand the thing up on it's side or upside down?
