If you mount the fan backwards the air will still flow the same direction it just will be very ineffecient because of the curve of the blade and could easily cause a cooling problem. In the 80's when serpentine belts started to show up with the reverse (counter clockwise) rotation water pumps I can't tell you how may cars started showed up in our shop that had cooling problems because these people put aftermarket flex fans on them that were designed for clockwise rotation water pumps.
