Coldest CPU?

[comrad]

What is the lowest temperature anyone has ever gotten on a cpu?

[kiwi]

Anywhere from -100C to -192C, LN2

You can not always measure temperature, besides many MB don't report core temps

[Gebba]

ln2 is the coolest thing i have known being used to coll a cpu whit.
i dont think any cpu can handle much more than -200 whiout die.

[comrad]

I know this, but what is the lowest temp ever recorded on a cpu?

[Vincentvega18]

well do you mean on or off?
Realistically it cant be far off ln2 temps with a yonah or something idling.

[g0dM@n]

Vince, what's the guy in your sig holding?

Comrad, good ques... I've wondered as well... I would be more interested to know what the lowest load temp was.

2 words... Liquid Helium. Someone with too much time and money needs to try that.

[gloatlizard]

it costs something like 30€ per liter:s damn

[gloatlizard]

this price simply stops anyone to try it, one time for all the service(dewar renting, lhe filling, cryogenic substances manipuation, transport) they asked me around 1000€

[Extera]

and how cold is that?

[Alex41290]

and how cold is that?

"Below its boiling point of 4.21 kelvins and above the lambda point of 2.1768 kelvins, the isotope helium-4 exists in a normal colorless liquid state, called helium I."

"Liquid helium below its lambda point begins to exhibit very unusual characteristics, in a state called helium II."
"Helium II is a superfluid, a quantum-mechanical state of matter with strange properties. For example, when it flows through even capillaries of 10-7 to 10-8 m width it has no measurable viscosity. However, when measurements were done between two moving discs, a viscosity comparable to that of gaseous helium was observed."

And, of course, the creeping effect .

Helium is so cool

[Extera]

4.21 kelvins? (0 kelvin is -273 celcius right?)

OMFG now that would be the ultimate cooling!

[kiwi]

(0 kelvin is -273 celcius right?)

Right

[Martijn]

Right

Why not make it solid helium... This is XS, right?? Helium becomes solid at 1Kelvin and 26 Athmosphere, otherwise it doesn't, but who cares

[Trouffman]

Liquid Helium isn't a super-fluid ?

Edit : Helium III probably :/

[Tyrou]

Helium II is actually a superfluid, that's written above

[Pete]

Umm XS has Members: 28,862 so if thus happend

All coughed up $30 USD

That be $865,860

If 1L of LH costs $30

Then we can buy 28,862L exactly and probs set some amazing speeds

heheheheh

[Extera]

Is LH not evaporating much more faster als LN2?

[Disposibleteen]

At temperatures that low the electrons slow down and therefore reliable movement of them is not a given. I would say that you wouldnt be able to boot a pc at those temperatures much less get carzy OC numbers out of it.

[zabomb4163]

liquid helium doesnt have much capacity

[perry_78]

As LH approaches 0k, it becomes somewhat of a rarity a frictionless liquid...

Listen to Tyrou

[Extera]

Well, here is your coldest chip!

(allright, it's not a cpu)

they used Liquid Helium.
man o man, what a wet dream

[g0dM@n]

I honestly don't see how a CPU would even boot at 4 Kelvin, or even 50 Kelvin... it's just way too cold... not to mention, do we even know what materials can handle that type of temperature (screws, container, gloves, etc.)?

[Big SturL]

Isn't it also so that at a certain temperature, everything gets conductive? Like plastic and rubber and all you can find on a motherboard.
