- the 'cold' side may drop below the 130°K which is the point where semiconductors (aka transistors in CPUs) stop being 'semi' conductors, and start conducting fully. Which is, for a CPU, not good.
There is no need to operate existing TEC's at their Vmax spec. In fact very few people (and a foolish few at that) do so.

Assuming these new devices behave similar to exsisting TEC's, it is only a matter of operating the device at an appropriate voltage for the application.
