I was thinking about what someone said in another post about building a computer inside a fridge for maximum cooling, and suddenly a thought popped into my head.

**LIQUID NITROGREN COOLING**

Hehe, that crap is like below zero, and if you pumped it through tubes with a pump like water cooling, your CPU would literally be frozen... Hehe, thats what I'm talking about!

Feedback anyone? Smile

Hehe, I know, but you could overclock it bigtime, and it could run at -20F... Hehehe, I like the sound of that! The only problem is, you would have to be ok with spending alot of money... But still, it's just an idea... Very Happy

liquid nitrogen is only cold if you let it evaporate, and if it evaporates then you need to keep adding more and more and more.

now what you could do, is something more along the lines of a refrigderator. laws of thermo dynamics state that if have heat it needs to go some where, so no matter what you do your going to need to either keep dumping more of something cold in there to keep it cold, or have a system (like a refridgerator or regular water cooling) that would esentailly transfer the heat from inside th case to outside.

if your going to overclock your going to run into stablility (after a certain point of course) problems no matter how cold you keep the cpu. It is more a matter of silicon purity then tempature.

though if you do want to keep dumping stuff in to your computer to keep it running cool I would suggest co2 (like the stuff for paint ball guns) before liquid nitrogen (it is cheaper) all you would really need it a water block to force the co2 through (and maybe a valve to adjust the flow for an optimal tempature)

ok liquid nitrogen would require a very different setup just by the liquid being -200 degree F or lower and the fact that any metal it cools will contract you wouldnt likely havea good contact on the cpu and heatsink. then theirs the little problem of actually supplying the liquid to the system. a bone maroow collection lab can use a 300 gallon tank in a week just cooling 1 freezer. so it wouldnt be economical to even both thinking about the tank space you would need to just keep the liquid nitrogen.

I was thinking about modifying a minifridge a while ago for my computer, but one of my friends pointed that out warm air and cold air can make water, so that would be another problem with massive temperature diffrences.

Do a google search and I'm sure you'll find at least one article out there where someone has actually been crazy enough to use liquid nitrogen to cool a computer. There was a real crazy person that got a bottle of some 3M fluid thats non conductive and had the mobo swimming in the fluid which was cooled I think with dry ice while the injected liquide nitrogen into some sort of cooler on the CPU. It worked damn well, but was only done for the glory of being able to do it.

If you don't open the fridge, you don't have that problem. You'd have to set it up with the cabling passing through a sealed port and CD drives in external enclosures, which these days is actually damn easy with USB/Firewire solutions (not so a few years back when people experimented)

if you put any pc part in a fridge yoou are going to have serious problems with humidity on the parts. every time you open the door it allows warm moist air into the fridge and allows it to condense on your pc not a good thing i would think

how about water-proofing all components, even the case, lol... then it wouldn't matter about condensation Laughing

depending on the setup it wouldn't be that bad. you wouldn't have to open the door that often and if you kept it in a nice minifridge that could keep a nice LOW tempature (well below freezeing) you wouldn't have to worry about water (it would be ICE.)
Though I'm still a fan of the Idea of low flow fans in a well sealed case (one air intake one exaust) and ventalation to the outside during winter.... or to the refridgerator during summer. and of course a nice big passive heatsink.

Never got around to it, though, like many of my half-baked ideas. I think it might've actually worked, if I put the cd & floppy drives outside the case. Best to test it with a junker pc first, though.

a company named Cryotech has been making liquid nitrogen CPU coolers for some time now... they just aint cheep. (I first heard about them my freshman year in college, fall 1999)

Well once you have the computer in a fridge, you'll be needing a dehumidifier for good measure.

Then a way to detect any moisture above a certain point would be needed. Have computer shutdown above the mark. Then the system is safe(er) when off if condensation occurs.

I was playing round with compressed air a few days ago and managed to get the temperature of some water down to -40c
