I can easily see boring a CPU sink as a simpler alternative as long as a
round silicone rubber chimney isnt required.
That may be possible with an old "block with fins" type heat sink but
many of the newer ones use a relatively thin plate/heat spreader and
tubes filled with a heat transfer fluid. The tubes bend upward to a
radiator in the normal air flow or with or have a fan mounted to the
radiator. Drilling/boring one of those would damage the heat tubes
and render it useless.
