Liquid Nitrogen Beats Air Cooling (Again)

The Muropaketti guys had already done this with their microprocessor. Apparently the next step was to speed up their graphics card to match.

    Liquid Nitrogen Beats Air Cooling

    Sorry, but this is high school physics.

    Obviously, it did freeze before shorting anything out. They would have to shut it down upon exhausting the coolant, so as not to overheat. Therefore, the condensation from the melting ice would not harm the board as there would be no power applied.

    Is it me, or is that guy pouring liquid nitrogen with his bare hands? Is he aware of the danger of getting that stuff on his hands?

    He has some measure of "protection" from the Liedenfrost effect -- if cold N2 gets on his relatively hot hand, it'll flash-boil and create a thin cushion of gaseous N2 that should protect his hand from the liquid to some degree. This can be demonstrated by a competent professional by pouring a small drop into the palm of the hand.

    Now, if his fingers slipped and the cup of N2 fell over his hand, he'd be out of luck... Wearing gloves in that case isn't enough protection, because the liquid will just run down the glove, under the cuff of the shirt, onto the arm. The best thing to do is manipulate the N2 dewar with a long pair of tongs...

    People have done dumber things before, like dousing their head in alcohol (to kill lice) then lighting up a cigarette...
