Ref-<Also compressors and the whole refrigeration industry is extremely mature and I would suspect all the parts that Kryotech is using is off the shelf, so I do not necessarily see a reliability issue.The concerns regarding CTE mismatches and thermal fatigue are just designs issues and they can be dealt with.>

I have never seen a cooling system failure. My systems used solid state Peltier coolers, or LN2 for cooling. However the electronic parts being cooled are subject to much higher failures rates than normal. [ The cooled electronics comprises less than 5% of the system, but accounts for 85% of failures. ] The failure mechanisms are corrosion caused by condensation( loss of vacuum), and thermal stress leading to sheared (or snapped) connectors and wires, delamination of circuit traces on PC boards,shearing of chip leads etc. Perhaps theoretically preventable, but it is a slow painful empirical process, and any design or manufacturing change brings fresh and new failure sites.

I am sure that if the reliability was not a headache, AMD and Intel would be selling Kyrotech based systems.If your application is that critical, go ahead and buy one. Even if it lasts six months you will get your money's worth.

Ref - <Improvements of 1000 times (several orders of magnitude)? Hmmm >

For my applications noise does indeed drop several hundred fold, improving detection sensitivity by > 40x.
