Phase vs. DICE temps question - Overclock.net

PR1M3R · 04-08-09

Just wondering what temps a nice cascade will get. I know DICE will get -70 give or take.

What kind?
I work on systems down to -190C.

Not really sure. I was just looking on HWbot and there was no DICE results for the chip I was looking at. I know what LN2 does, but there were some Cascade results and was wondering how it would compare temp wise to DICE.

I would assume a single stage

Hmm? A single stage cascade? An auto, you mean?

The question is, what temps will a nice cascade get?

Single Stage -30 to -60C
Cascade (CO2) -70C
Cascade (Ethylenne) -95 to -110C

It depends a lot on heat load. And I'm not an expert, but I've seen a lot units on differents forums

If you want really cold temperatures with a single compressor, you're going to have to go with an auto-c. Basically it uses a mixture of gases with a lot of pressure, creating excellent temperatures, depending on the tuning of the unit. This being said, you should get one made by a reputable builder, because they can be pretty dangerous if not done right.

Also be prepared to spend a good chunk of money on an auto-c ($800+).

Autos are sweet until you change your chip or voltage. The difference in load means re-tuning and that's a big enough pain in the ass on an SS let alone an auto.

I'm very confused to see comments like this. Other then the information that an autocascade requires a mix of refrigerants.
Autocascades like any refrigeration system are built to a certain specification. This is the load range. A properly built system can easily cover a larger range of loads, autocascades especially can cover larger ranges due to the refrigerant mix. A lower load then the max load simply resulting in colder stack temperatures, and lower pressures and less work performed by the compressor.

dice is cheaper phase is colder. Pick your ammo.
