Nice, I thought I couldn't be the only one wanting to tinker with it ;-)


I thought of using a CPU cooler too, but not too seriously, I'd have to admit. I haven't been able to find much about people doing it, and what's out there is old. I'd have to make a custom bracket solution or something, right?


There are solutions for controlling the pressure in the pipe as far as I understand. Essentially you want a near-vacuum in it. This is achieved by bringing the working fluid to a boil while the top end of the heat-pipe is open. When the working fluid has evaporated and displaced the air inside, you seal it. When the heat pipe cools and the working fluid re-condenses, you have your near-vacuum.
