first of all, what the hell does james bond have to do with anything?
anyway, phase change is extreme cooling, most systems manage temps anywhere from -20c to -60c, there mainly reserved for extreme oc-ing. the only way to get a system is to have a guy build one for you, or you build it yourself. It's kinda like water cooling, only you use gas instead. (the gas is changed into a liquid before it hits the cpu.) phase change has been around for a while btw.
