The Alfa fan geometry looks also suitable for both applications so I think it is going to work. Also, a fan can produce a much bigger volumetric air flow in a push configuration compared to a pull configuration.
Now that I look at the picture of the fan I posted assembled in front of the condenser, I realize that the geometry is definitely meant for a pull application and not optimal for a push aplication. Too bad... I guess I'll just need to wait and see when the day comes when I finally get the car running, weather or not I run into heat issues.
