Phase change noob...

post #1 of 2
Thread Starter 

A few q's

 

1) how loud is it generally

 

2) how much will it cost kinda?

 

3) how many types of phase cooling are there? (I have seen single stage cascade ect)

 

4) anything else I need to know?

 

Thanks

Phase change units can be relatively quiet or quite loud. It depends on the type of compressor used as well as the capacity (amongst other things). Older, lower power SS units can be found for as cheap as $200 (and sometimes lower), but they're only ideal for low load testing (most common form is single threaded benchmarks) or older chips. New single stage units start around $600 on the low end and get up to around $900 on the higher end. Note that price is not always indicative of performance. Cascades usually start around $1300 and go up to about $1800 for the more powerful rotary units.

Most common in this hobby are single stage units. Cascades include anything with more than one stage (two stage, three stage). It is possible to make a cascade with more than three stages but those units typically draw thousands of watts of power and are complete feats of engineering. A good single stage will load with 300W at around -35°C while a good dual stage will load around -85°C with 300W. Triples can sometimes do -110°C and colder. It all depends on the builder, the gases, and the components. While the theoretical side of refrigeration works out quite nicely, real world results can be quite far from calculations so the experience of the builder can make a world of difference.

Some of the builders that frequent this site are SDumper, NoL, Grey Mole, RunMC, and a few others.
