All fans that I know of of pullers because, if not, they would be pushing against the intake of air past the fan from the outside. I can see of no beneifit in having two fans. If you will look at the configuration as is, you will see that it pull the max amount of air thru there now. In 1984, they used a 2speed fan which they did away with in previous years. Good luck.
