What direction should the fan run?

The electric radiator fan as we all know is mounted on the back side of the radiator. Is it supposed to run in the direction to blow air into the radiator, therefore working against any natural air flow from driving? Or is it supposed to be sucking air through the radiator working with the natural air flow? Mine is working to suck air through the radiator into the engine compartment and I just want to know if its running backwards.
