   I tried that and it helped more than just a regular heat sink, but not as
well as an extra large heat sink. I'm not happy with the thermal coupling
of the Peltier device that I used, so perhaps it would work better if it
wasn't attached with thermal tape (e.g. use thermal compound instead). The
heat sink alone solutions I used all had an appropriate amount of thermal
compound.

   We already do, but when the system is busy, you aren't halted very often,
so the effect of this is minor.
