You seem to be using the term "temperature" in a different sense from "that which is measured with a thermometer". All computers that I'm aware of generate heat, and in fact heat removal is the major obstacle to faster CPU frequency. In your sense, the coldest place on Earth is a petroglyph, a stone carving. -- Gene

If you generalize "temperature" as in statistical thermodynamics, then you should be able to do better.
"temperature" is essentially the change in energy content w.r.t. change information content.
Modern computer memory systems are quite good at storing huge amounts of information with very little energy, so they should have a very low "temperature".
In this case the "shielding" is the height of the barriers.
Basically, computers couldn't possibly work unless the "effective temperature" (in statistical thermodynamics terms) of the information stored in their circuits is exceedingly low. Otherwise, they'd constantly be making mistakes & be useless as a digital computer.
