Why -100Celcius? - Page 2

post #11 of 18
ok i couldnt find much because alot of the things i found needed like subscriptions to certain news letters and stuff which i didnt feel like doing but if you research enough you can find the same ones and do it your self, ok

serprisingly enough it was rather hard to find actuall no **** documentation on this stuff but i did find a few things that talked about similer stuff that was good reads that ill link here,

one thing which most here allready know is thermal noise that has to do with the electron skipping from its intended path and causing problems ...
http://www.ph.tn.tudelft.nl/Courses/...p-Thermal.html
theres more to it but that was a quick little definition that i found and its straight forward and this link goes along with it but it is rather old stilla good read though
http://www.trnmag.com/Stories/2003/0...on_011503.html

this i think has been posted and is slightly off topic but still kind of cool
http://www.sfgate.com/cgi-bin/articl...f163743D48.DTL

from my understanding is that with lower temp's you can reduce the possibility of errors in the chip at higher voltages and temperatures do to
well one the thermal noise or whatever, also due to the fact that there is no perfrect solution to cool a chip there for with standard cooling you are going to get geradients in the temperature and sometimes i guess these could be really high isolated temps and ithink that it helps in this at extreme points and thus helps with maintianing a stable clock speed


i dont claim to know much this is just a little couple of table scraps, please find more and share with us

There are several advantages to low temperatures. Things contract and get closer, you have less electron migration, and you can pump more voltage.

You might or might not care about the science behind it. The bottom line is, if 1.4V will get you to 3.4Ghz @ 60C, 1.4V can get you to 4.0Ghz @ -100C.

Can you have Phase Change, Overclock, but only raise your voltage by .1-2. Would that help with your CPU's life. Also, if you have cooler temps will that help your CPU's life, or only lower voltage? Thanks. And, now I see, I was wondering why people want -30C when Apex Ultra's provide 0C temps with there Hybrid Water Cooling Model.

People with phase usually run 1.6V+

In chem I learned that absolute zero temp is the best conducter for electricity. So why not go for it?
Working Great!

Because absolute zero or 0 kelvin or -273.15C CANNOT be reached with current technology let alone near that in a computer; -100 to -150 has been reached with liquid nitrogen and cascade cooling (2 or more phase change coolers 'tied' together). If i recall the closest science has gotten is around 2-3 degrees above absloute zero and at absloute zero all electrons stop moving so is that a good thing for a cpu or anything for that matter? Also if i recall to reach near 0 kelivn you need serious pressure and a perfect or ner perfect vaccum on the object/matter.

It is impossible to reach absolute zero now and in the future. It is as impossible as going infinity M/s and having an infinite mass. Just not going to happen.

Absolute Zero = Minimal possibly Kinetic energy! any way, to be able to get near 0K on a CPU that puts out something like 150W+ you will be spending more $$$ each month on the energy to power your cooling device than your sys is worth!

scientists have gotten "2 BILLIONTHS" of a deg above 0K but that was w/ an object that produced no Kinetic energy! (or heat) they had to use Lasers ( something about manipulating the vibration of the Atoms/Electrons) and on top of that they had to isolate the device from all heat sources!!! So no touching Not even w/ a 10ft stick
