-200 degree Deep Freezer!
 

After gogling and get some very bad Chinese pages, with the only thing legible being things like -164 degrees Celcius, I finally found a link to a page with deep freezers claiming they can bottom out at -200 degrees!

Maybe, instead of re-inventing the wheel, one of you guys can just disassemble the thing and use it to super (duper?) cool the heck out of your CPUs?

The link is shown above.

Let me know what you think.

The only wall you'll find with these units is the price tag. You could contract a refrigeration expert like ruffus, sdumper, runmc and some others to build you a cascade phase change system that could be tuned to suit you're needs for much cheaper and avoid some of the cold bug issues.

A small sized Ln2 plant probably goes for the same price of these cryo units.

Hmmm... good point.
