hattermadattea Posted January 8, 2003 Posted January 8, 2003 I'm not good with forums, so I'm just starting my own topic. first question I'm looking for a liquid nitrogen cooling kit, or anyone who's made one as an experiment. It shouldn't be much different then water cooling, except a much bigger compressor, and heavy duty pressure lines. second question Liquid nitrogen cooling would be a very extreme cooling system. Would it be too extreme? Causing thermal shock or fully freezing the cpu Quote Share this post Link to post Share on other sites More sharing options...
smeghead009 Posted January 8, 2003 Posted January 8, 2003 im pretty sure noone makes a premade Ln2 cooling kit, you could probably make one out off copper piping an a industrial pump designed to pump Ln2, you would have a hell of a time controling the condensation.

Crackers Posted January 9, 2003 Posted January 9, 2003 I maybe new to this forum but the problem with Liquid nitrogen is the fact its EXSPENSIVE and hard to get in small quanitys.. If you were asking for a bulk tank you may have an easier time but its gonna cost you an arm and a leg. Secondly With a cpu being that cool you would achieve super cunductivity which by all means would allow you to over clock the cpu to extream results like a 3.06gig ht p4 would possibly be able to hit 1 tera herts Now here comes the problem.. You wont find a mother board able to over clock a chip that much due to power consumtion. Secondly you would also need to super chill the whole mother board and ram. Last but not least. You will have as mentioned above you will have condensation problems SO in other words only way to do it right would be to encapsulate the entire board with some sortof heatransfering epoxy and submerge the whole board into liquid nitrogen and do it that way.. please don't mind my spelling and grammer mistakes errors and everything else wrong with the post.. I suck at english allways have allways will =( Anyways Have a nice day. Quote Share this post Link to post Share on other sites More sharing options...
ATI Radeon 8500 Posted January 9, 2003 Posted January 9, 2003 Yeah noone I've ever seen has made a permanent LN2 cooler. People just make tghem t od oextreme OCs, then they use more passive cooling like water cooling for everyday life. BUT...You could go with vapor phase cooling (Vapochll, Prometeia, etc.) which cools at around -15 C or -20 C consistently and possibly even lower than that.

Ronin Posted January 9, 2003 Posted January 9, 2003 terahz lol. heh, yeah, follow ATI's advice. There is no reason to use liquid nitrogen other then you can say "I use liquid nitrogen cooling" too many problems. If you have the cash do what ATI said.

Pendragon Posted January 9, 2003 Posted January 9, 2003 hmm i thought they were crickets! LOL and on top of condensation and etc good luck getting a license to even purchase the stuff. Quote Share this post Link to post Share on other sites More sharing options...
Ronin Posted January 9, 2003 Posted January 9, 2003 no no, it was coachroaches and then crickets. He got had twice if you need a container for liquid nitrogen I happen to have one....umm..dont ask Quote Share this post Link to post Share on other sites More sharing options...
ATI Radeon 8500 Posted January 9, 2003 Posted January 9, 2003 I won't...But...As Pendragon said, have fun getting rid of the condensation. You'll need t oge ta license to buy this 3M crap liquid for electronics testing that you'll constantly use that rings in at $1,000 a gallon last time I checked, and you'll need 2 gallons consistently. Besides that, you'll have the ugliest comp ever that you casn't take LANning. Plus getting LN2 is extremely expensive and you'll need another license, plus to buy the containers will cost a lot unless you're ronin. The simple solution is go with a Vapochill, great cooling, looks good, and it's around $550 for the best looking best performing version of it. There is the Prometeia, but it is moe hardcore and you'll need to mod it into your case unless you use the generic case that can come with it. Anyway Vapor Phase is basically a refrigerator in your case, s oyou can still impress people with it if you want to... Quote Share this post Link to post Share on other sites More sharing options...
KraZy Posted January 11, 2003 Posted January 11, 2003 Ok... I've see low temp cooling before, and I can tell you one of the better ways I have seen it done. But liquid CO2 or O2 is probably a better way to go. Prev comment on chilling the whole board was correct. In order to do this, you can use an industrial strength plastic bag and cover the whole board. In order to prevent condensation in the bag when it is immersed in whatever cooling medium, you have to displace the air and the water vapor in the bag with nitrogen. Not only is the nitrogen relativly inert, it will not hold water vapor like plain air. (pure O2 is NOT an option here.... excess condensation==shorting==boom) Now, provided that you can get the bag sealed around the wires for the board, and you do not get any air leaks, you can use a styrofoam beer cooler to hold the whole mess. The way I saw it done, CO2 was just dumped over the board while the benchmarking was being done. I am sure that you can invent some kind of circulation system. Still, condensation is a problem, so what you have to do is -cover- the pins of any removable IC (BIOS) and the cpu with AS3. Cover the sockets and chip to prevent any water vapor from condensing around the -important- parts of the computer. I think that if you had the money, you could actully cover the whole board, but that is specualtion... I think even on the best attempt the life span of the boards being tested were about 3 hrs. The problem? Condensation. But the point remains that it can be done. Quote Share this post Link to post Share on other sites More sharing options...
vyroburn Posted January 11, 2003 Posted January 11, 2003 ARE YOU PEOPLE STUPID? there is no way to put Liquid nitrogen in a cycle system you canot compress it of get it to run as thou a water colling setup would do. you canot just get a bigger compressor.becuase liquid nitrogen connont be compressed. and if you do try to compress it.... if it heats up to the slightest degree it will expand and make what ever it is held in explode........ many many many times to i have to tell people this and they just do not listen. liquid nitrogen is used only for short periods because it evaporates so very quickly.......... DIDNt you high school chemistry teacher tell you this????? get a vapo chill man... I doubt that you will even need lower temps than that you probibly only you use your computer for word processing and doing your vocabulary homework..... so why bother Quote Share this post Link to post Share on other sites More sharing options...
