Saturn, as you know, Peltier coolers are completely different that Kryotechs. All the problems that you noted are due to lack of proper design not an inherent problem with the cooling concept. Re << I am sure that if the reliability was not a headache, AMD and Intel would be selling Kyrotech based systems>> AMD and Intel are chip makers not computer manufacturers. Kryotech has an OEM relationship with AMD. Mani

Saturn V [ 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. Very nice summary of everything that can go wrong when subjecting electronics assemblies to unnatural acts (cooling). Right on with what I've seen. Since, in this little sub-thread, the vote is 2 to 1 in favor of not liking the idea of such unnatural acts being subjected to computers for 6% performance improvement, I vote we should drop it. Tony
