That's why they teamed up with 3M, to develop thermal conductive compounds.

What if they used a different medium, do you remember the solder iron sold on TV infomercials, battery operated, instant heat, melts solder?
The tip was made out of a novel type of silicon that multiplies temperature. If you put that between the layers of the chips and apply cold temps, which would be multiplied by 10, you could get an effective thermoregulator.
