phase change cooling

[ollithemagicbum]

does anyone here have experience with one?

i know it's ridiculously expensive, but it has excellent cooling.

i was wondering if anyone here tried it, or do you stick with water/air cooling?

if it wasn't so expensive i think i would try it. once i get a apprenticeship in refrigeration i would/could actually just build one from old parts. i would just need the block. i already have my ODP (ozone depletion prevention certificate so i can go buy the refrigerant i just can't legally do anything with it.

here (http://www.thebestcasescenario.com/forum/showthread.php?t=609&highlight=R2D2) is some phase change

here (http://www.thebestcasescenario.com/forum/showthread.php?t=8155&highlight=phase+change)is the completed worklog of that same pc

I don't have any experience other than reading about it on the web. I've read that you have to be very careful about condensation around your cpu or you could fry it.

i only read about it on the web too. this one site got the processor down to -29C. :O

i wish i could remember this one site i saw, i will look for it later, but he a double stage phase change. that means when the first stage cools it to (i don't remember the numbers) -20 then the second stage kicks in with a different refrigerant and cool it to -101 i think is what it hit.

Extreme Overclocking Forums (http://forums.extremeoverclocking.com/index.php) has a section dedicated to Phase Change, Dry Ice, LN2, Other Crazy Stuff (http://forums.extremeoverclocking.com/f183.html) and building them. There is even a guy who builds and sells them to people. They are all custom and pretty specific to your needs. This isn't an ad by the way. I was considering buying one, but opted out of it. I was looking at a $400 phase changer, which isn't too bad considering a good water cooling will cost you a little less then that but not get anywhere close to the temps. Just have to keep in mind the power it uses. If you are considering this, talk to DrewMeister on those forums. Hope this helps. Good Luck!

TGS had one but he didn't think it was all that great. He sold it.
