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

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.
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.
