Bad plan. Heat sinks depend on surface area to dissipate heat. They put
fins on them to increase the amount of surface area. Cutting up your
heat sink, thus reducing the surface area, will make your heat problem
much worse instead of better.

Good point. Maybe put it in one side of the case and drill holes on the
other and have a cross wind over the pills.


You might try doing what computer manufacturers do and look for heat sinks
to put directly on the ceramic IC package. An easier idea would be to go
hit a PC component place for an appropriate sized cooling fan to install
with screws straight into the top of the heatsink fins (a-la CPU heatsink)
to force air into it.
