Integrating Peltier cooling directly into chips

AMD has filed a patent for integrating the Peltier cooling effect directly
into its CPUs. Currently most Peltier coolers work on the heatsink of the
chip, rather than directly in the chip. This might be something they are
getting ready for when they transition to the 65nm process. So far they've
been able to get away without too many problems at the 90nm node, but
judging by what we're seeing from Intel, it's only a matter of time before
AMD also experiences the same thing; and it might experience it by the 65nm
node.
