Liquid Nitrogen cooling??

[Sworkhard]

Ever try liquid nitogen cooling. It'll take your cpu donw to -220 c

[Christoph]

CPUs die (or age *very* quickly) at -50 °C and below. Some people do use LN, though.

[UserName]

Is there a source for that info. I have never heard that. I have heard of many projects super cooling CPU's but never a limit on how cold you can go.

[Morbid]

Is it possible to buy LN without some sort of permit? I dont know if they have limits on the people that can buy LN, like they do on some "bomb making materials".

[Yodums]

It depends what kind of Liquid Nitrogen your using but the project I saw the temps went down to -74 Celius. At about anywhere beyond -50 your CPU can start be too cold to damage the cpu.

Can't remember the URL for the site but they had two extreme cooling projects both labeled Mission Submerisble. They made a block for the LN and proceeded to submerse the motherboard and cards in 3M Flourinet and dry ice, both dielectric. They did not leave it on long enough for fear of damaging the CPU and other circuitry, they were so scared in fact, they used a Digital Doc, never let it get beyond POST.

i think this (http://www.octools.com/index.cgi?caller=news.html) is what your talking about

[ButcherUK]

Thermal contraction is the issue. The Al or Cu interconnects contract differently from the silicon and also from the ceramic. Can cause the chip to litterally rip itself apart.

[docJ]

Not only will the chip self- destruct because of thermal expansion
problems, but the mos transistors are doped to work near room temp and will not function at all or very little at 50K. So for standard chips it can be to cold to work.

You can buy LN from most welding supply stores. It's been a couple of years since I had to buy any (work related), but no special permit was required. The only special "thing" you'll need is a container for the LN. You'll need a specialized thermos bottle for the LN, or it'll all boil out before you get home. The bad news is that these special LN containers are expensive and you may end up spending more on the container than it's worth.

[Sworkhard]

Liquid Nitrogen is generally a stable liquid at -220 c or lower. So, if it is possible to keep it at this tempurater then the cpu should dive to -220 at full idle. -74 is probobally at full load. From what you have said though, if it just jumped down to -220, you could probabally take the core out of the packaging because the core shrinks faster than the packaging. Am I correct? Thanks for the help. I was curious if there were any complications with this system and I guess there are.:(

[Sworkhard]

You've never read of these temps because one's computer won't boot with a broken CPU.

[Sworkhard]

Liquid Nitrogen is that cold,correct.

[Slain]

Actual boiling point of LN2 is -195.798 C
hehe I am so picky :)

Great stuff to mess around with tho, my fave is the jet propelled ping pong ball although instant ice cream is cool too.

Cold wont hurt the CPU. That's an old wives tale.

In the article above he had the CPU down to -150C with no harm to it. His MB died cause he went too fast.

Deriding those of an opposing viewpoint doesn't help your postion much.

I would never recommend that anyone bother going below -35°C. It would require a great effort for a debatable return at a high risk.
I've never frozen a core to death, but the arguement seems logical. If you want to risk it, then by all means go for it. I'd love to see what happens (good or bad), but I don't see any logic in it.

No, what you have set forth before us is a theory and dumb luck. Like the guy who got the knife right through his head and lived, I bet if you did that to ten people, there is a very high chance all ten would be dead. To prove a theory, you have to get the same results after multiple experiments, so UserName, I set forth this challenge before you, you do this multiple times with multiple systems and your theory is proven, until then, I suggest you cut back on the sarcasm and bolstering the fact that since one person did it, all can.

And I return the challenge to its rightful resting spot.

Until then the EVIDENCE, not the hearsay or opinion, stands with me.

So maybe you haven't read what Vash and I have. My bad.
When I said the arguement seemed logical, I meant that the difference in the contraction of the components of a CPU (Cu,Si,etc..) at extreme temperatures would cause the chip to rip itself apart.
If you have two guys (Cu and Si) running a marathon (changing temperature), and one runs 1% faster than the other (difference in density vs temp), there won't be much of a difference after 30 seconds (ambient temp), but there will be a large difference after an hour (extreme temp).
Sorry if that was unclear. I'll fix it when I can see it clearly. (not drunk, just tired)

do a web search on Absolute zero.

If that dont answer your question post a new thread, OK?

[RainMaQer]

You do know that you come off rude don't you. I asked this because I was wondering if running a cpu at -220 would have cause the particles to slow down... degrade performance maybe...

What does it matter how good the theory is if observations prove it wrong?

If you have read it from a credible source share it and let me start apologizing and thanking you for the learning.

If you read it from someone who told others who said… whatever, than shouldn’t you ask yourself if it’s true?

So what happened? Did it boot? Did it it go into Windows? Yeah it did. Booted easily with the CPU at about -150C(block temp), but you cannot understand the language anymore. The screen suddenly turned alien into us. Inside Windows everything was corrupted. We cannot understand a damn thing! Checksum error was up. We could go into the BIOS and change stuff but everything was different. The keyboard types different letters. Pressing letter 'a' gives you a different letter and same goes with all other keys. Tried reflashing the BIOS but floppy drive won't work either when we attached one. Besides you cannot type the right command as it gives you different keys. In other words the motherboard was stuffed. Somehow the CMOS was damaged by the extreme temperature. Everything seems to work fine. Video card, RAM, CPU all worked properly after drying and testing them in a normal 'unsubmerged' system. Although the HD was corrupted. The only question though is...was it the extreme board temp that stuffed board? Or was it the CPU's extreme low temperature that caused it? Could the CPU's sudden temp spike corrupted the CMOS? Funny thing though the CPU is 100% working fine up to now. - From an LN2 experiment

They also say LN2 will not damage your CPU or crack it if cooling is done gradually, that means you cannot use LN2 alone, you have to use other forms that gradually get you down to a temp safe enough to introduce LN2, such as water, flourinet or dry ice.

Now, prove me wrong by doing it yourself.

~Vash~

[RainMaQer]

I'm missing where it's not possible:
All elements in their most stable state have the same entropy at absolute Zero. And The entropy of all perfectly crystaline substances tends to zero at absolute Zero.
Now... beyond this... what happens at -220. Could the errors have occured when the particles moved slower due to such low temps? Maybe altering the MICROSCOPIC design of the processor?

[UserName]

Your Quote is in error. THE VERY NEXT SENTANCE SAYS " No cracks whatsoever caused by the LN2"

The CPU went to -150C and worked find after words. That selfsame article continues and says so.

You have tried to misquote to bend the evidence to your ends. You do not seek truth.

A CPU can be cooled without harm to at least -150C.

Reading, it's the key to everything. Yes the core was not cracked thanks to GRADUAL COOLING but the system did not work properly at those temps. What good is a system if you can take a PIII 550E to 3GHz but then not be able to do anything because programs are now malfunctioning thanks to the extreme cooling?

What good is it?

I'm reading all the posts with interest. Before anyone starts doing anything with LIN, please read the posts in the thread Liquid Nitrogen, started by me in this forum.

If a CPU/mobo was greatly reduced in temp., i.e. -150 C, then the resistance of the circuits would drop. This has the advantage of letting OCs super power up without excess heating. (Its the resistance to the current that causes heating.)
However, it is this very resistance which lets transistors work. If the resistance drops, the vary nature of the microprocessor will change. Not at the atomic level, but its electrical characteristics. You may even begin to see some super-conductivity in some doped elements of the chip (I doubt it but it is possible)

This may explain the behaviour of the supercooled CPU posted earlier. As different resistances change, the architecture (electrically) will also change, so in fact the machine code being executed for the chip, is not then designed for that chip, and gibberish is the result.

To answer another question, Absolute zero, if ever reached will exhibit zero atomic and molecular activity, even the atoms intrinsic vibration and inter/intra molecular bonds will stabilise.

The posting referring to differential thermal expansion/contraction is true. If the materials in a CPU have even slightly different coefficiants of expansion, then the chip will self destruct.

You can try an expiriment with LIN.

Cover a rod of copper (high C of E) with butyl rubber (low C of E).
Drop the assembly into LIN. As the temp drops, the copper shrinks and the rubber becomes hard and brittle. As the temp. drops even more, the rubber shatters and breaks, as the copper keeps on trying to shrink faster and more than the rubber, and pulls it apart.

You can acheive gradual cooling using LIN, by using the cold gas phase produced when the LIN boils at room temp. This gas (really a mix of cold gaseous nitrogen and water vapour from the air) is at a low temp of between -40 to -80 C, but has a very low specific heat capacity, so it doesn't take the heat out of the chip very quickly.

[UserName]

Doug;
I think you forgot the part where mass collapses if all atomic activity stops.

The CPU in the article never had a problem. It went to -150C with no issues what so ever. He pulled it out and it worked fine. The fellow poured LIN over his MB and it cracked. That was the only reason for his problem.

These motherboards and CPU's are routinely cooled to these temps and work fine. Stop saying, "Thermal contraction will break it" if it isn’t true. It isn’t. The materials are different and a fellow cooled it and had no problems running it after it warmed back up. That’s change down and back with no harm.

The burden is on you to show how it will harm the CPU, as it didn't in this case.

Read the article. He is going to do it better next time.

As to the dangers of LIN, some people can’t learn unless they feel pain.

There's a difference between debate and flaming. Debate involves attacking ideas. Flaming involves attacking the indivdual that has the ideas.

The line can be fine, but here you see it clearly laid out. We only support the former.

Thelemac

[Intraveinous]

Different elements expand and contract at different rates and ammounts when supercooled. Fill a bottle to the top with water and cap it tightly, then put it in the freezer. It will expand and possibly pop the top or break the glass. Same basic concept here. The silicon, aluminum, copper, ceramic, etc etc etc all will react to the extreme temperatures differently. I do not know exactly what happens to each element at that temperature, but the science tells me that it will probably be bad. I'm not dissing anyone's argument... I understand the "SHOW ME" standpoint. I personally have no plans in the near future to cool anything to below -50C, so I end my participation there.

Yes, if you poured LIN over the system, it would freeze the mainboard, but if you were just cooling the CPU, then it would take a long time to completely freeze the board.

It wouldn't freeze your hand immediately. A few drops of LIN wouldn't really hurt. I certainly wouldn't advise putting your hand into LIN, or keeping it under a continiuous stream of LIN .

[Teacher_Doug]

I don't understand what you mean by mass collapses

see the ref http://www.sun.rhbnc.ac.uk/~uhap057/LTWeb/Absolute.html

and
http://www.public.iastate.edu/~physics/sci.physics/faq/neg_temperature.html

where they discuss absolute zero and

negative temparature

As far as the survivability of CPUs at -150 C, I take your point about the article supporting your discussion, but I havn't seen it repeated (I certainly can't afford to risk my CPU), and if you can't reproduce an experiment, it's not Science, just an opinion

[UserName]

The theory of mass collapse is based on tempature ~ energy ~ motion. If temp = 0 then motion = 0 and electrons have no energy to resist the attractive force of the nucleus. Atomic collapse. It seems from a quantum point of view this is not necessarily true. I had not heard of negative tempature, thank you.

Now I know you are playing games with me. You are trying to see if i will notice.

Science is not based on ones will. If some do not will to reproduce the experiments, they are still valid, as valid as all others. Even if it is never repeated it still stands as true untill other results are shown.

Surely such a logic error is a test as such an educator as your self would not make it.

[Teacher_Doug]

Hi UserName

OK, If I understand you , you are not talking about the colapse of Mass, but the compression of matter, where all of the sub-atomic constituents of an atom are compressed into a dense substance, this I agree with. I was confused as to your earlier meaning, I thought you were referring to a disappearance of Mass, which would not be possible, as being an intrinsic attribute of matter.

In the second thread of the discussion, I wasn't trying to trap you with logic. Any professional scientific journal may report on the results of a single experiment, but the results will not be used to prove/disprove any theories UNTIL a peer review has taken place, AND the experiment has been satisfactorily reproduced. I take your point regarding the lack of will, but this has been a major influence in scientific development. The results of an experiment must seem valuable, otherwise why do it in the first place. I just don't regard this super-cooling proceedure to be that valuable TO ME. Obviously anyone more dedicated to this area may disagree. It is then up to them to reproduce the experimental conditions, and prove to the rest of us the truth or falsity of the theory.

LN2 cooling doesn't kill CPUs and that's the damn truth! :D
I've done that twice WITH THE SAME CPU (1GHz AXIA TB) and it's still alive :) It doesn't work properly at stock voltage anymore though. Needs some 2V Vcore for stable operation now.

Yes the temp change is huge, but please remember that it takes a while until a copper LN2 container cools down (it has quite a big thermal capacity). So the container is like a buffer there.

Also the actual CPU core temp will be nowhere even near -196C. It's a lot higher than that.

SO IT CAN KILL YOUR CPU!!!!(or at least damage it), DON'T YOU GUYS USE COMMON SENSE?????? sorry for screaming, but when you need to up CV to 2V something tells me you killed a part of the CPU.

Smells like contradiction to me, NO I'M NOT THAT SMART.
First you say he cooled it down to -150C, and then you say his board cracked when he poured LIN over it, In other words VASH was right when he said it could be done by GRADUAL COOLING, Also(like VASH said before) WHAT'S THE USE OF A CPU TO POST @ 400000 Terraherz WHEN IT DOESN'T RUN @ THAT SPEED!!!!!!!???????

I'll try to make things a bit more clear, different materials contract at a different rate.
Here's a list (expansion of 1metre of material @ an increase of 1C):
Material.......Expansion in metres......Expansion in millimetres
Rubber...............0.000670..................... ............0.670
PVC..................0.000150..................... ............0.150
Aluminium............0.000023..................... ............0.023
Silver...............0.000019..................... ............0.019
Brass................0.000018..................... ............0.018
Copper...............0.000017..................... ............0.017
Steel................0.000011..................... ............0.011
Brick................0.000006..................... ............0.006
Glass................0.000003..................... ............0.003
Porcelain............0.000002..................... ............0.002

You need to know there are internal changes when either heating or cooling your CPU (every dedicated OC'er knows that you're able to OC more with better cooling) NO I DON'T KNOW EVERYTHING BOUT THAT, BUT I know there is a LIMIT.
If you want to understand why there is a limit you need to know how a CPU is made, something you might want to read first is an article about Electromigation (http://www.csl.mete.metu.edu.tr/Electromigration/emig.htm)
OK after you've read the electromigration part (which is a PROVEN fact, and which will show you changes occur inside a cpu.....see figure 3) you might be able to understand the following:
(I kinda suck when it comes to explaining $#!T cuz I'm Dutch so I wont be using technical terms).
Lets say (see pic): RED is conductor X, BLUE is conductor Y and GREEN is Insulator Z.
If you got that part, lets say Z and X contract at the same rate (to make it easier) but Y contracts more, (assuming pic A1 is the CPU @ normal operating temperature) you'll end up with either:
B1, B2, B3, or B4 when "super cooling" the CPU.
If B1, B2 or B3 happens your CPU "probably" will be fine afterwards, but if B4 happens (what probably happened to macci's CPU) your CPU might act funny (like macci's CPU) or don't work at all (see pic C1, where some particles broke of and fell in between the broken conductor Y).......Probably the reason why macci needs to increase CV (due to more resistance).

OK I hear you screaming what's the white part in the pic, it could be:
1) a vacuum
2) Z (the insulator)
3) Air
To be honost I don't have an answer to that, Anyway if its neither of those, YOUR CPU WILL CRACK.....think of bi-metal (the stuff used in thermostats)...it bends due to a different rate of contraction.

If I wasn't clear just ask me and I'll try to explain that part again.

LIKE I SAID BEFORE: THIS IS JUST USING COMMON SENSE.
To make it more clear: I'm a drunk OC'er that gets things done with one eye closed (that doesn't mean I know everything or even come close!!!!!):beer: :beer: :beer: and yes I'm drunk while typing this:p

I'm getting sick of these threads about ppl that "have done it again".

In the first thread mentioned they failed. They published it.

It doesn't matter how many times someone failes, it's that is can be done.

we blew up like 15 rockets on the launchpad getting to the moon. Does that mean it can't be done?

Yes LIN can kill your CPU, so can; dropping it, OCing it, throwing it, water cooling it, sitting on it, sauceing it in a blender, changeing a HSF... insert your horror story here.

The final point which has been proved is that it DOESN'T HAVE TO KILL YOUR CPU! There is no physical reason that a CPU WILL be damaged. It may be, if you do it wrong, but it don't have to. They don't wear out at that temp, in fact the oppisit is true. They run better longer.

Read a book.

[CreePinG_DeatH]

Forget the Hype behind Liquid Nitrogen cooling. It isn't easy, feasible or practical yet. If there comes a time when processors are made out of some super material, or maybe on a quantum computer, then start worrying about whether it's going to kill the CPU or not.

I mean seriously, if LN2 kills a CPU or not, is anyone going to go out and use LN2 to keep a cpu overclocked to a certain temperature? I hope not because it will cost an arm and a leg and in 18 months you'll have an easily cooled cpu that is the same speed.

MastrMuff;

These 2 going on 3 pages of posts do nothing more than discuss if it's possable. Not probable or good or smart or anything else. 2 pages of foolishness to show it's possable.

I am reminded of back when water cooling got started and everyone said it was stupid and will kill your PC.

If you could LIN cool your PC for 100$ a year in LIN and a 200$ cooler would you? At what amout would you say yes?

WTF no one said it wasn't possible, It was about the fact that it could KILL or damage the CPU, As we all know a LOT of Japanese folks have done it, time after time again...
BUT IT'S STILL NO PROOF that it can or can't KILL, damage or shorten the life span of your CPU

How about my theory that it can and probably will harm the CPU????
Give me some feedback....Please

[CreePinG_DeatH]

well then my 2 cents would simply be sure it's possible. However this "ghetto" approach of pouring LN2 into a copper bowl is stupid and will your cpu, if not severely damage it. But if your funds are high enough to even play with LN2, not to mention skilled enough, then go for it.

In theory you would jsut need a similar setup to a Vapochill with a more powerful compressor and some type of self adjusting valve that can regulate the flow of LN2.

Plus you'll need an assload of testing. This "I've done it 2 times" crap doesn't mean anything from a scientific point of view. Most likely 100,000 tests would have to be complete to produce an accurate measurement. You would need to know if you have to slowly warm the processor up as you would have to slowly cool it down? Can the cpu even be turned off altogether? Will the cpu need to be warmed up as evenly as it is cooled?

It's very possible. And if you really want it to work just need money. Of course after all the testing and money is spent, there still is no guarantee that it would work... which would really suck for whoever spent the money on it wouldn't it? :-)
