I did a search of this forum first before posting this. Ironically, there was nothing even given for the term cryogenic anywhere on this forum. So it seems like this may be new territory.
EDIT: It would have helped if I had spelled cryogenic correctly!
After seeing all the discussions of extreme phase-change cooling, I wondered if anyone here really ever considered building a system capable of cryogenic temperatures. We've all seen the accounts of builders on the web using LN2 or even Helium for short runs to set records for overclocking. But what about the possibility of actually building a cryogenic system that could run 24/7?
I'm certain such a system would require multiple stages, and probably in combination with autocascading techniques. And the thing is, I think some of the advanced builders here actually have the skill to do this. So what would it take to build a system to stop the fires of hell, so to speak. If anyone has looked into this, let us know what you've found out.
In the long run, I guess this thread will be primarily theoretical. Although it would be nice if an actual guide could be established from this.

EDIT: Because of the repeated questions I've had about vortex tubes, please don't ask me any questions about "vortex tubes" without FIRST having looked up "vortex tube" on the internet. There's way TOO MUCH INFORMATION on the subject to have to keep covering the same issue.
EDIT: Throughout the course of asking this question, I have pursued many directions of attacking a solution to this. In some ways, my posts may seem rambling. I acknowledge that. But I think of greater importance are the various studies I've found be researchers probing similar goals. As a result I've made frequent use of patent searches.
The greatest objection that has been raised is the amount of energy that would have to be consumed to provide such a level of deep cooling. It is here that I've sought understanding of how various devices and technologies that I had become aware of have been shared here. Many of these investigations are beyond the scope of what is typically pursued by users of this site. But then again, if that weren't the case, many of them would already have cryogenically-cooled computers. So here are some of the links I've found related to this topic:
