A interesting discussion indeed!
The Wiedemann-Franz Law may bring more light in this discussion.
Gustav Wiedemann and Rudolph Franz found an empirical law of physics, 
concerning the ratio of the thermal conductivity  (K)  of a metal to its electrical 
conductivity (Ã), being a constant times the absolute temperature.

Good and easy to understand descriptions can be found not only in:

enjoy,
