Liquid Nitrogen Cooling

[LiamApex]

Would it be possible to use liquid nitrogen in a actual  cooling loop providing you used all metal tubes and full metal blocks and reservoirs etc. in theory could it be done and would you even need radiators or would you just keep pumping it round

[flibberdipper]

No. You would constantly need to be adding more unless you were able to re-condense it back to liquid LN2 form. And I don't even know if that's possible to do that, or pump it around.

I would have to be extremely well sealed, actually it might explode because of the pressure of the vapor

As long as the pump doesn't freeze and the LN2 syas at -150ish  then it should be good.

Most of the cooling from liquid nitrogen comes from it evaporating quckly, if you close the loop it won't cool much at all. it basically boils and takes all the heat away normally, but by boiling it needs to evaporate. which when it does you basically need it to condensate again for what you need EXTREME amounts of pressure and i mean extreme. from example take a can of compressed air, it's not cold at all, but if you spray it it on your hand will freeze your skin.

hmm ok well what is the coolest liquid that will stay at a liquid at both below 0 and 50ish degrees

you need something like this https://www.youtube.com/watch?v=Z_X_hgtlJpA

You can't cool the evaporated nitrogen down to its condensation point through normal PC cooling. You would need a very high-end heat pump to do that, at that point you're very far away from your "standard" PC water cooling loop. So, no.

Well... how much money do you have...

if you want low-ish temps oil submerged pc is also an option.

Liquid nitrogen boils at -195°C, so in order to keep it from evaporating, building up pressure and making the whole loop explode, you would have to keep it below that temperature at all times. This would require an extremely complex and power-hungry cooling system that would need all kinds of pressure valves and other safety features to keep it from blowing up in the event of a power outage. The other problem would be that the whole thing would have to be insulated like crazy to keep the condensation from flooding your PC with water. Overall, I'd say its not possible.

liquid nitrogen is a coolant that behaves exactly like the coolant in your refrigerator or air conditioner but does so at lower temps. when pressurized and condensed it releases heat to it's surroundings and when depressurized and evaporating.boiling it absorbs heat from it's surroundings. similar temps to LN2 cooling can be achieved with what is called Cascade cooling, but it consumes an enormous amount of energy to the point where more cores or more expensive parts are more price effective

[Briggsy]

you'd be better off running a loop outside of the case and having the radiator and reservoir in a fridge, than trying to close loop LN2.

[Sauron]

It's impossible, to keep it in liquid form it would be too cold for the cpu to work. Freezing electrical components can be as bad as overheating them. Not to mention you'd need a machine that can actively cool down the nitrogen in seconds, which would be incredibly expensive.
