How does phase change cooling work and why is it not very popular?

1. They cost a crap load of money to purchase.
2. they are loud.
3. they cost a lot to run.
4 they are popular with certain groups, but not for everyday computing.

first of all stay away from frozencpu, they cost too much and if the product arrives faulty you have to pay for shipping back to them again.

as for phase change, there are other ones but they cost alot, this one takes alot of room, we are waiting on rcb400 to see how it does, unlike others its not no loud much, needs no maintenance.

these type of cooling are for overclock enthusiast.

Phase change cooling works just like your refridgerator...it's the same technology and parts. Many DIYers actually build thier own systems with mini-fridge parts. It's essentially a liquid cooling system who's liquid is chilled way below room temperature. The tubes are thick because they HAVE to be insulalted, I'm not gonna get scientific on you...but uninsulated pipes will cause water to form in yor computer. The loud noice comes from the compressor kicking on and off as it cools your liquid.

This is a solution sutable only for OC freaks that need something more maintainable than liquid nitrogen and dry ice. It's a very small niche market and is unlikely to ever gain a significant market share because the skill, time and effort required to OC a CPU that hot will always remain a rarity.

hey the rcb400 is suppose to be like $300 to $400, thats very close to frostbite cooling here, if you can pay $50 more then frostbite, no maintenance, and keep much better temps, that alone is worth it, the option of pushing the OC higher is just icing on the cake IMHO.

if for $50 more I can have load temps of say 50c vs 75c, its well worth it IMHO.

You are correct sir. I had no idea there was a phase change solution in the works for such a low price point. It looks like it's actually a real product too, not made from mini-fridge parts. Maybe this product can eek out some market share. It does make a compelling arguement. I got a Cool-it liquid cooler because it is maintenence free and keeps the CPU super low (42 idle, 52 load w/OC) but this thing can get you down to 27. That's craziness.

Now I'm going to have to keep an eye out for this thing.

That mini phase will be interesting, wonder if it will keep an i7 with HT on better than this??  This is before I added the XSPCrx360 radiator, so need to retest, should be 2C or so lower now on load.  lol

You don't need phase changers no more, especially with the cool running i7 processors based on the D0 revision.

We have been hitting 4.6GHz at 75'C full load on liquid cooling.
