Do you hear the internal fan running and feel the airflow out the vents ? If not, then you need to take the projector apart and replace the fan. No external fan is going to make enough difference to matter. Even if you feel airflow, the fan could be dirty or otherwise not moving as much air as it needs to. Ideally, a repair shop could take it apart, clean the interior, test the fan and the temperature senor, replace what was necessary ... and not charge a fortune. In reality, they would definitely charge a fortune. More than the projector is worth and more than a new entry level projector would cost.
The beauty of it being essentially useless is that you can take it apart yourself without worry about making things any worse.
