Dry Ice + Coolant or ln2 in WC loop?

post #1 of 21
Thread Starter 
This is a very hypothetical question, but I think about stuff like this a lot so I thought I'd ask. Not sure if this should be in DICE/LN2 forums or this one...

Anyway, I was wondering what would happen if you put antifreeze, water, and dry ice into a water cooling reservoir (or just straight up liquid nitrogen). Would it create volatile pockets of air that would blow holes in your tubing or something like that? Or freeze the coolant? I just know that there are uses outside of tubing for these materials and was wondering if they'd work in a water cooling loop. Just wondering if someone could shed some light on that? Thanks!

Never tried that before, but basic chemistry tells me that water + solid CO2 = CO2 gas, which probably means that in a closed environment, cause an increase in pressure and possibly rupture your tubings.

Maybe if you tried it in a large open reservoir to allow the CO2 to escape...

What if you kept the top of the res open to allow the gas to escape? In a completely closed environment, the PC would probably explode, lol.

If you put DICE in the reservoir and closed it, it would build up pressure as spultz mentioned. How much, I'm not sure. Drop some Dice in the toilet and it bubbles right away and evaporates within seconds.

Not sure about LN2. I've never tried pouring into water. I don't like wasting it.

What if it were only ln2 in a loop? No water or any additives?

it evaporates far too fast unless the entire system is near -190...which is not really possible for an entire WC loop. plus that stuff is really expensive compared to water.

best bet is a chiller with a beefed up A/C chilling the water

ln2 is not like water to run in a loop

YOu would freeze the hoses and everthing else... plus LN2 evaporates super fast. If you did that on a closed loop it would probably blow it up before it even got it cold enough.

With conventional WC gear it is probably a bad idea. The res / tubing will crack, the blocks will distort, possibly enough to rupture, and the pump, god knows what will happen there.

It would be a cool experiment, but don't be surprised if it goes horribly horribly wrong.

About the only good thing is that a minor leak of LN2 isn't a problem, as it will flash to gas pretty quickly. I'm not sure what a major LN2 spill directly onto electrical components will do though. Possibly another interesting experiment?

LN2 does not stay liquid at room temperature.
