In this application, a fan is definitely the first thing to try (assuming you don't have a mechanical issue that is causing the heat problem to begin with).

If you don't have airflow, you're relying on radiative cooling, and in that case surface area is very important. But in order to get enough radiative cooling to make a significant difference, the motor has to be hot enough that it will likely already be permanently damaged.
