Thinking of getting one of these for an AM3 motherboard (Biostar TA785G3)

After looking around it seems like for AM3 socket the fan on this cooler either points up or down rather than into the rear case fan. Can anyone confirm if this is true?

As an illustration, this is how I want it installed (this is in an Intel socket):



Is this possible with AM3?
