Liquid nitrogen cooling

[blake99]

Does anyone have any info on the proposed liquid nitrogen cooling solutions that are down the pipe (so to speak)?

This should put simple water cooling to shame

thats not possible, you would get massive condensation. just look at how phase change units are built, and those only have to protect against -50s temperatures.

it is possible and people have done it. You just need to insulate properly.

If you properly insulate with grease and foam you shouldnt get any condensation forming.

In the link above they got a p4 to 5.25 Ghz at -190C!

You could do it, but you need one hell of a dehumidifier to get the moisture levels down.

Have a friend that actually ran his pc from inside a chest type freezer.
Its still working after over a year.

he said down the pipe, in the sense of circulating liquid nitrogen. not a pour in the cylinder with a cup solution. circulating LN2 would cause condensation problems that cannot be overcome. plus I dont think any kind of pump can run with LN2.

think before you post dude, everybody knows LN2 can be used for cooling, but the OP was asking for a standalone LN2 cooling solution. I don't think you want to pour a cup of LN2 every 2 minutes when you're on your computer doing work.

I'm not sure how you figure a ln2 cooling solution from "down the pipe". "down the pipe" is not a common saying for a cooling loop. Even googling the term returned nothing with respect to any kind of loop. It that saying some kind of local/regional slang?

 

[JAG87]

down the pipe refers to liquid flowing through a pipe or tube. at least thats how I interpret it. but hey I might be wrong. I'm pretty sure he referred to a loop since he is said "that would put water cooling to shame".

Not likely to be practical anytime soon for a work-a-day PC. One of those refrigerated cases should be as far as a sane person would be willing to go - and one might even question the sanity of that...

possible and practical are 2 different things......
For everyday use not practical and $$$$$$$$$$

Actually the term "down the pipe" in the context I'm reading in the OP, refers to various thoughts and ideas that have been circulating around. In this sense it does not refer to a physical pipe you would pour something into.

There is a limit to how cold you can go and have a working system.

The most common ways to cool the large supercomputers were immersion (rare because it can damage parts over time) and refrigerated air and liquid.

Seems the air is the most common with liquid a close second.

I saw one case where they made a heatsink that covered an entire motherboard and sat just 1 micron above the board. It was being used in a foundry where the board would be subjected to very high temps.

Another used refrigerated glycol circulated around parts held in a vacuum.

I can't really see any home user making use of things like this though.

"circulating" he-heh. "pour" he-heh.

Come on guys i am surprised none of you linked this site yet.

This is the place to go for extreme cooling.

But phase change is more practical than LN2/Dry Ice, as it is cheaper and will last longer.
