My chips get barely warm, and I piggy back them.  A fan doesn't hurt either.
Not to mention how MUCH SIMPLER it is to just stack the ICs  rather then
wiring up an entire new socket and wasting board space.

The thermal dissapation is only a problem with chips like the TC442X which
get blazing hot in normal use.  The UCC3732X series stay cool if you're in
their operating limits.
