Greetings all,

Has anyone built or worked with liquid nitrogen?

Would you care to share your experiences?

I saw one article from someone from Hungary, but I didn't really understand how he built it. Any other articles I missed would be nice to see also, if you know of some.


Thanks!
BJL;)

A few super impressive overclocks have been done using liquid nitrogen mostly in the far east however these PC's generally do not appear to work for a long period of time perhaps its a condensation problem

i would think that you would have to be extremely careful, because a sudden change in temperarure in any component could crack it

It'd be a problem, keeping enough liquid nitrogen handy...

Most of the ones I've seen have been a 'Lets see how fast we can get this thing to boot and run WCPUID and Sandra so we have proof' type a things... Metal sleeve wrapped in insulation that they just pour the liquid nitrogen into and boot the machine. That's how they've been able to get T-Birds as high as 2.2GHz I think... Been a while... Condensation is a HUGE problem, as there is typically a layer of ice on the BACK of the mobo. It's been discussed before though that when you get something that cold, the silicon shrinks so much that it can actually tear things apart inside the die. So yeah, typically they're not any kind of long term solutions, nor are they really very good for the processor/rest of the computer.
Peace

liquid nitrate is only good for about "one hour of overclocking bliss." Some sort of vpochill or using a refrigorator is the best your going to be able to do for any long term situation. Those LN2 projects can also end up costing a lot of cash.

isn't there a way you can use a solid metal block with poor conductive uses, use a small amount of LN, and insulate it enough to keep temps as low as possible?

Well, no, because you can't insulate it from the cpu...(well, you could, but what would be the point??)

I remember an article by a guy from New Zealand who used 2 gal of flourinert ($500/gal from 3M) and liquid nitrogen in an attempt to get the ultimate cooling system. He submersed his mobo in the flourinert (that's what it's made for) and had a rather elaborate setup. Sorry I don't have a link. The flourinert ended up gelling in his pipes from the liquid N2 , but he got some mad temperatures.
I can't in good conscience recommend this to you, but now you know.

there is an article on LN on the main page, it is just a box on the cpu.
