Which direction should the fans be facing in order to exhaust air?

    The sticker should be the way the air flows. That's how it is on my fans.

    The sticker is irrelevant.

    In fact I'd say 90% of all OEM CPU cooling fans have the sticker on top, where you can see it, but they all blow DOWN onto the heat sink.

    There should be an arrow on the fan case, somewhere around the outside, that
    shows the rotation of the blade, and the direction of flow.

    Not if you don't know which way the blade turns.

    But yes, I would go with the airflow towards the motor mount
    theory.

    You can tell which way it turns by the way the blades are curved, which in turn tells you which way it blows. It would not make any sense to curve the blades one way and turn it the other way, it would not move hardly any air.

    True enough.
