Liquid Nitrogen VS Phase Change

post #1 of 16
Thread Starter 
I know liquid nitrogen is by no means a widespread cooling and that is has lots of kinks....but what is more effective? Liquid Nitrogen or Phase Change?
post #2 of 16
Liquid Nitrogen will get you much cooler, but only for short suicide runs. Phase change will not go nearly as cool as ln2, but can be run 24/7.

Yeah, I knew liquid nitrogen wouldn't last long, but I've heard rumors that it's OCed an Intel to 5.0 Ghz.

liquid nitrogen,unless you use the liquid nitrogen its self in the pase change system..lol then thay are the same.

but most phase change systems run around-30c to -90c... liquid nitrogen is at about -198c. geuss which is better.

here take a look at this http://news.softpedia.com/news/7GHz-Pentium-6202.shtml

LN2 = -186 C
Phase = -40 C (or so)

The Ln2 is a couple hours of use while phase is 24/7. Go for the phase.

Phase change gets P4's to 5ghz, Liquid Nitrogen will get good chips to over 7 ghz.

Then also there is DICE, or Dry Ice, which also works very good, but also a short term cooling solution that will give you temps in the -80*c range

Liquid nitrogen has taken chips far past that. A few years ago Tom's Hardware got a chip to 5.5Ghz. People have gotten 6ghz on ln2.

Chilly1 charged a Phase/Cascade system with LN2 and was achieving an evap. temp of -300F, Pure LN2 in a container will get you temp's in the -186C range, mass produced Phase change will get you temp's in the -30C ~ -40C range and Custom phase/cascade will achieve about -100C depending on how well the unit is tuned and the component's used.

As other people have said LN2 is great for suicide run's but is isn't practicle for everyday use as it evaporates pretty quickly.

Phase change can be run 24/7 and is alot more practicle

can you put ln2 in a phase change and not have to worry about evap

You cant put LN2 into a normal phase change system as the compressor isnt strong enough to compress the nitrogen back into a liquid.
