The 9V battery makes the fan spin slower but still does the job. As for the fan motor burning up, that can happen if the motor over heats (recirculating old hot air). I have mine secured With JB weld at the bottom of the visor. It's at a slight angle with a small open space behind it allowing cool air to be pulled up from the bottom and blows on my face. As I stated before the 9V battery makes the motor spin slower so The breeze is not so strong to be annoying.
