If the compressor gets really hot it might help to have a fan blowing
on it.

The compressor (when integral with the motor) is cooled by the
refrigerent going through it, and therefore expects to be hot.
A fan blowing at the compressor won't do anything significant
(maybe a few tens of watts at best, when the thing is generating
several kW anyway). The heat from the compressor is carried away
by the refrigerent and dumped in the condensor, together with
the heat extracted from the evaporator.
