By reverse it I was actually meaning take it off and mount it reversed, so the blades would be correct (though it doesn't make all that much difference).

Despite the lack of shroud, it would move the general airflow in the correct direction to make use of the heatsink.

Yes, it might only be 80-90% as effective as using it correctly, but it's still good
