5 GHz Project: CPU Cooling With Liquid Nitrogen

Nice one!

Hahaha. I have seen this earlier on the net but I saw these Japanese guys bring it to over 6 gigs! Now that's what I call EXTREME overclocking. By the way their P4 looked something like a toast when they got it wrong while testing the process out. What a waste! LOL

JAN :D

it was only stable at 5.4ghz...but they did hit 6ghz. pretty awesome.
 
How can the CPU work at such a cold temperature? I would have thought it would break LOL!

It probably would break if it was just sitting there being chilled. It was generating heat though dont forget :)
 
lol, it wouldn't have time to generate heat at -190 C!!

It doesnt need time. Heat output is constant (or roughly so, if you really wanna get nitpicky we can bust out Conservation of Energy)
 
Ok Ok, I have had enough of that topic in my Science Lessons!

What I'm trying to say it, wouldn't it just be frozen through and through?

I'm confuzzled lol!

the chip itself should be able to handle any extreme low temperature provided you don't subject it to sudden forces like dropping it. Whats interesting to me is the ceramic chip casing should become a supercunductor at those temperatures and yet it still functions properly

Agreed but once you get to isnanely low temperatures, even vibrations may be enough (insanely low = appreciable distance of absolute zero)

So what if it's frozen? It doesnt have mechanical parts (not in the traditional sense)
 
If it did "freeze" solid, it would still run i think. But you would never be able to shut off the computer again, or lower the temperatures. The chip would start to "melt" and there would be lots of water all around the socket and on the inside of the socket. Cold is good, freezing i wouldn't want lol.

Freezing metal doesnt neccesarily involve water ... especially at appreciable quantities near absolute zero ('sides any transition would be done gradually and you'd have heaters in place :)) ... i hope :P
 
i thought if it was frozen literally, ice crystals would start to form. then rising temps would melt them. i dunno...i rarely hear of this happening, never seen a pic.

Yer that is extreme overclocking :rolleyes:

I qualified my staement my noting that it would be at appreicable closeness to 0K. Naturally (rather, ideally) you'd do that in a vaccum type condition at which point ice crystals wouldnt be too big of an issue ... sides dont forget that air is liquified at those temperatures)

no 5h!7 ... thats why its called absolute zero :P

you keep mentioning absolute zero...a prometia gets nowhere near those kinds of temps. i can't see the connection... :confused:
 
1. I wasnt talking about the prometia
2. Prometria is out of business tmk
3. I wasnt commenting to anything you stated intially.

oh i thought this was about prometia's/vapochills/nitrogen cooling. i see lots of vapochills...been a while since i seen a prometia advertised.
