LIQUID NITROGEN cooling

take a to pluto along with thousands of extra batterys and ups and swap batteries every few minutes or so.

Or you could save a lot of money and a lot of energy and use a cryocooler here on earth.
 
Nothing on earth will ever be absolute 0. At some level it will be touching something that makes heat.
 
Not absolute zero, but coolers have been made that have reached a few milli-Kelvin. However, at those low temps there's very low, or no, load.
 
Anyone who can get their hands on liquid nitrogen could clock a processor rediculusly high, a real feat would be to do it with air cooling (or even non refridgerated water)

That and finding a proc that can handle the voltage well (medium/long term) heehee

Does anyone know a way to get some liquid nitrogen??????????????

Generally speaking, "if you need to ask....."

Thus so far so good. But why it still won't work?

1. Lets get back on topic
2. Gravity dont like stuffos floating around up there :P

But yeah ... scrolling down some more ... lets get back on topic. Now. ;)
 
n00b!

Do you even know what kelvin is...n00b! Zero celcius is 273K. If it was millions of kelvin then it would be millions of celsius too. Also there are chemical environments that can create absolute zero (-273K).

You have just been... urmm... 0WNED!

When Yeti comes on you will be owned (provided he feels like replying). If your chemical environment exists it certainly isn't absolute zero.

Alright three things (I'll restrain myself):
1) Get some glasses - milli is a bit different from million
2) I am far from being a "noob" in the area of thermodynamics
3) If you know so much, then tell me this - What exactly is temperature?

Edit: Also, if you can provide a link to these so called chemical environments that can achieve absolute zero I would be very interested. Of course I can provide links to the cryocoolers that have achieved ~ 4 mK if asked (mostly dilution refrigerators)

EDIT:I reliezed i might get banned soon ifi i keep posting like this, so just ignor this post, And obvoily i was yelling at Andy for being.. well.. you know...

Just putting my two cents in: temperature is the average kinetic energy of all the molecules in an object.

Alright, to get on topic which is the THG article on the LN2 overclock (just in case you forgot) here's a couple things that I thought -
The temperature of the CPU is not the -190C, that's the temperature of the cooling head. If the CPU were at -190C it would require over 9 liters per minute of liquid nitrogen. Also, I doubt that they used temperature sensors (thermocouples, thermistors, thermal diodes, etc) that were properly calibrated and thermally anchored for use in cryogenic temperatures thus leading to even more scepticism of that temp. Also, I'd like to know where those load numbers are coming from.

If you really want to try to get it, Praxair and Air Liquid are a couple of the largest liquid and compressed gas distributers. If they'll actually sell to you in very small quantities I really don't know.
