Fan Rotation ???????

I'm tired of having problems out of my Taurus electric fan so I'm going back to my regular fan. I have a serpentine belt system so I have to use a reverse rotation fan. My question is that I have 2 fans and I'd like to know what the difference is:

Both have 5 blades

One says G89 on the studs, and the other says B91. Anybody know which one would create more air?

The fan that has more blade angle and larger blades will produce more airflow. Not sure about the numbers you have up there.

They look to be the same angle on the blades, but I haven't measured the blades themselves. If there is a difference it is a small one because I would have noticed with the naked eye.
