View Full Version : Liquid Helium

Well, if I am not mistaken, liquid helium is something like 2.17 K. This is just 2.17 degrees above absolute zero. Was just thinking if anyone has ever read anyone trying this, running a processor at -300 or so Centigrade seems a little funny.

i doubt it. however i have heard of computers in kryogenic chambers...

I was just gonna say, they use the stuff to cool super conductors. Some colleges have the stuff available to chem lab, anyone here in college and wanna try something? lol.

i may have acces to a collage chem lab lemme check i aint in but my bro is hehe..

youd need a pretty condtant supply of helium, think of the amount of heat that would go into your comp with a 300*c temp difference. besides doesnt the athlon use some copper, and copper actually gets more conductive after a point of severe coldity

still, it would be pretty cool

youd need a few gallons. best way would be to make a heavily insulated box and evaporate the helium there to drop the temps then have a funnel or tube where the rest of the helium runs onto the cpu. that way the enviroment wouldnt be to diffrent and you had some residual effects. and all metals become more conductive the colder you get them. liquid helium is hard to maintain also you have to chill a dewar to keep it reasonably without to much loss cus the stuff boils off at any hint of heat

most metals become more conductive, some become super cxonductors (0 resistance) some just get very conductive. however, copper is the exception, at some insane temnperature it is extremely conductive, but if you make it colder, it actually becomes less conductive, i dont know why.

-300 C would be quite a feat... considering -273 C is absolute zero.
Yeah, that would be really cool! :D
Something we would have to figure out first though is how to get the atoms to move less then not at all... :(

today in chemistry class i learned that...
all metals become less conductive as heat rises, and more conductive as they get colder
all semi-conductors (transition metals) become less conductive as they get colder.
also... diamond is the best conductor of heat... and um... that's it :D

yeah, but, the exception is copper, it will hit a point whree it stops becomming more conductive, adn starts to become more insulative. im not shure if copper is the only one. never fully believe what you learn in science classes, they always try and make it simple to learn, adn thus leave out alot of info that is needed to apply it to the real world. teachers are not always right. last year, my physics teacher, who is supposed to be really smart and such, tried to tell me that voltage is the speed at which electricity travels, and that is why high voltages kill you, cause the electricity goes through you faster! what a dum a$$. at that point he lost my trust and respect. i mean, he was a physics teacher! then this year my chem teacher tries to tell me that the added metal to iron to make steal is zinc!

i would assume all metals in the same column as copper would get less conductive when it gets colder i have my chem book right here lemme check. Nothing in there but i would assume copper, gold, and silver all suffer this flaw

getting the temps is fine but dont cpu's tend to die really fast after -50c or so?

they could go backwards:rolleyes::beer:

don´t think so, I think people on the forums have achieved -70°C temps and still quite alive (the cpu)

i doubt youll freeze it to death, theres not much that will die at cold temps i dont think, might be wrong, uless one of the materials starts expanding, adn bursts th packet or something:) some of the materials might superconduct, or the chip will stop eoring if the atom stop moving:) it would be the first case of a cpu dying of too much cold! atleast in the forums

You're not actually gonna try this are you?
...But if you do, we want pics :D hehe
Good luck
