Anyone Here Using A Phase Changer?

im just wondering how many people are using them, they dont seem that popular around here, but why not have subzero temperatures all the time without the need to refill the pot with ln2 or anything?

Well they are expensive, loud, and use quiet a bit of electricity. And big.

And they don't give as good temps as Ln2 by a long shot.

i can like with the first bit xD but still you cant use Ln2 24/7 can you?

And you cant use Phase either 24/7 if its sub ambient b/c of condensation concerns I would imagine....

I use single stage to set up the rig for ln2.....

i was told you just had to fully sleeve and insulate the evaporator

Ln2 24/7 would cost a LOT of money. Someone can chime in how much Ln2 they use for a benching session and tell you the cost. Ln2 is a fully 100% hands on every minute to monitor temps and pour into the POT. Warch one of the benching sessions we do live here.

It comes down to phase change can be used 24/7. Ln2 or DICE can't.

Why do you need -40C CPU temps for your PC for daily use? Just curious.

And insulate the Mobo bottom, top, in the CPU socket, around the socket etc etc. Phase change, Ln2, DICE all have a tendicy to make the smoke come out, like a top fuel nitro dragster. They go boom pretty often.

Phase is usable 24/7, people do it.
You have to insulate the hell out of the board, but it's doable.

You can get -20 to -40*c off a single stage, depending on the unit and the cpu in question.
Dry ice gets you -30 to -65*c at full load, depending on the pot and the CPU.
LN2 gets you down to -195*c depending on the pot and the CPU, only AMD and a very few select intels can go that low though.
LH gets you to -220 to -250, far as i know that's Phenom II only territory.


The further down that list you go, the higher the operating costs.

That really is a huge misconception.
Phase can easily be used 24/7. We have developed evaporators and mounts to the point that almost no insulation needs be added past what we provide; precut and ready to go in many cases. A little bit of grease in the socket; easily removed with canned air later and clamp on a mount; ta da easy.
As far as size, people see these big benching units and think that's all we do. I make tons of units to fit into V2000 cases or even smaller area's then that. Cost isn't nearly as high as well. People spend $400 for a Kingpin pot, and for $150 or so more they could have 24/7 subzero.
