Yes it is, its a step above phase change. personally dont know much about it except its called casacde cooling

Basically a cascade system is a series of phase changers. I am by no means an "Alternate Cooling Expert" but from what I remember it is just a series (usually 3, for TRIPLE cascade) of phase changers cooling each other. The lowest I have heard of are -150c units. But ridiculously low temps like this are usually measured at the evapourator head and the actual die temp of the CPU is usually much higher.

Expensive, and power-hungry. And not even spectacually fast - chips are not made to run that cool. But if you want a status symbol, you cant beat it.

they have a BIG article about this at some website, i think its at XS. there's a lot of wisdom from some great overclockers, including chilly1 among others.

for more info on making your own cascade and just researching it, click this link.

there's a billion different types of ways to build your own cascade. i'm in the middle of it right now.

i'd say 0 degrees is fine like really, even if you overclock to 200 ghz on phase change it will go up to like 30 degrees from -50 (i think thats how cold phase change gets)

oh well i'm stickin to air

200 ghz? go up 30 degrees? lol. Phase change can get like -70+ if you do it right.. And why would 0 degree's be fine? Even with 0 degree's your not gonna be able to get close to what a phase change at -50 would be able to produce..

i'm going for the magic -100c, then i'm going to start asking a few of my friends if they want to donate some of their computer parts to "science"

Chips run better at lower temperatures*. When you get a cpu extremely cold, the electrons are able to travel easier through the transistor gates, even at higher voltages. This is less signal degradation within the chip, and you can overclock higher. Techinically, you are correct. CPU's are not "made" to run at extreme temps. However, if everyone had a phase change unit they would be.

*There are a few cpu's, mainly AMD's, that have "cold bugs". Meaning, the cpu's will not boot up below certain temperatures, usually around -50C or so.
