I have known about phase change cooling for some time now, ive wanted to do it but seeing what the units cost really makes me uneasy. 900 dollars for th VapoChill LS! So I have thought about actually making my own for these reasons. 1. I want to learn more about it 2. I it is cheaper?!?! 3. It could be fun 4. Insane clocks at sub zero temps Plus for my next case mod project, i'd biold it right into the chassis. Can anyone reccomend any good tutorials, information, anything about this?
