now there's an idea

It would be a first huh?

Malecky,
If and when you are going to supacool an XP CPU I suggest you forget the LN2 and buy some dryice + ethanol

its a proven fact that XP CPUs can't stand LN2 temps. Sampsa killed one xp2000 when he cooled it down w/ LN2 (that chip wouldn't even post when ln2cooled). And I know that this has happend more than once..
And even if it will POST it may not OC any better than w/ dryice cooling. The chip just can't handle those extreme temps. POS AMDs LOL (oh and I'm not going to even mention the little L2 problemo..oops I just did that )
The Good Old ceramic Athlon THunderbirds chips were different though. Those chips just loved LN2

So in case you dont want to risk your chip use dryice. But if you like challenges go ahead and get some real LN2. It may work (might work better if you pour it little by little so that the container doesn't quite reach -190ish).

anyways good luck bro

OK, thx macci, I didnt know that

I will ty it with a Duron 600 and then measure how low the temps go... I Can make a different canister that the temp doest come that low.

Let see if I can make 1500mhz with a D600

Hay in case you are intrested in ln2 cooling you might want to check out this little post I just wrote over at vr-zone forums:

Thats great stuff Macci

You mind if I post the link in a new thread also??

very neat, macci. interesting read

Everytime I have done LN cooling, no marks were left over. If your just going to LN cool the CPU, there shouldnt be much of a problem...just dont use your main rig. The motherboard can get pretty messed up (cause the water vapour in the air around the LN capsule freezes, and then lands on the area of mobo around the around the CPU).

I am surprised people are losing chips...I have only LN cooled a Palomino once ( and a tbird twice before that....and the original celeron experiments before the tbird) but the one time I LN cooled a palomino it went as planned......of coarse I didnt do it half a dozen times, and I had a substantial amount of past experience, but I think it would have been more of a mounting problem then actual cooling problem with those people who busted their :banana::banana::banana::banana:.

p.s. Even though there were no marks, I still wouldnt use someone elses hardware, unless you can afford to replace it.

Regarding the shrinking issue of the container. You dont need to solder it at all. The tube will shrink more than the base so all you need to do is heat the tube in the oven, chill the base with a little LN2 and youll get a pretty tight fit push fitting the base in. Let the LN2 shrink fit it in place. Instant seal - any small gaps will be frozen shut so no leaking. Pre cool the container using a small amount of LN2 while its off the cpu then put it on top and fill her up.

This is the method they use for fitting train wheels btw.

If you make the base about 0.5 - 0.7mm bigger than the tube diameter at ambient temp then the cooling / heating should take care of the rest.
