Subzero cooling in vacuum.

[Kevin.K.N.]

After seeing one of the last videos of ltt I though wouldn't it theoretically be possible to make sub zero cooling be possible to achieve without condensing in a vacuum chamber where it is all dry and no humidity ? (Would be a fun challenge to see linus take on)

It'd actually be worse because the only way to cool in a vacuum chamber is by radiation, which is horribly slow compared to convection or conduction.

 

Unless you mean putting the thing in a vacuum chamber but having some working fluid transferred via tubes.

 

EDIT: I do want to point out there's a cheapish, easy solution to protect bare leads from water as long as you don't anticipate needing to change out any of the soldered on chips: conformal coating.

I think if you were to place it in a vacuum chamber, while the CPU would be fine with it's actively cooled, there would be no air flow around everything else so you'd have overheating issues with Voltage regulators, memory, M.2 drive if it's susceptible and so on.   You could try putting it all in an air tight container and filling it with argon (welding argon is very cheap).

Well that was busted pretty quick. Back to the drawing board.
