Hi Jick,

I only mentioned that because the way things are here, Volts would probably be looking for pre-used aux fans. These used fans were most likely pulled out of old cars and therefore, OEM in nature and not the aftermarket kind you described. Being OEM, they're only designed for single polarity and airflow. At least, that's what I think.
