Are you talking about your AC and Heater blower? Or the fans on the radiator itself? If your not loosing any coolant, I wouldn't worry about it unless the smell is driving you insane.
The only thing that brings coolant inside the car's interior is the heater core. You might have a small leak at one of the hoses, causing it to leak onto the header.
