Inert Gases (like freeon)

[Will]

Does anyone know if Inert gases ( like Freeon) work well for cooling if used in a cooling system?

Yeah, but the cooling system has to be designed around that principal of phase change. The Vapochill system uses that type of cooling, and some people have made home made ones, but I don't think i'd jack with it...water is much easier. Not to mention, I don't like the idea of breathing freeon if there was a small leak or something.
