I was trying to find the best liquid for heat transfer and came across mercury(13 x thermal conduction than water!). The problem is mercury's boiling point is 357 Celcius. Anyone of you guys with sufficient physics/chemistry knowledge to figure how low pressure a vacuum needs to be for mercury to evaporate at around 40-60 Celcius? It may not be possible

But even if it can't be used for a heat pipe, what about just for a pumped cooling system? Silver heat sinks, mercury proof clear tubes, it'd be the most hardcore liquid cool on earth. Combined with peltiers it could work as low as -38.9 Celcius (freezing point of mercury).

I realize the dangers.. It's poisonous, and quite electrically conductive, but modding power supplies isn't exactly safe either
