Most cooling fans are optimized to push air in one direction. You can
make air flow the other way by running the motor in reverse, but
properly designed fan blades have an airfoil profile on them that is
much more efficient when they're run in the right direction. Some fans
may allow you to mount the blades the other way forward, and if you can
do that you're in good shape. I know that the Honda Civic fans I picked
up a few years back do not let you do this (not without modifying the
hub drastically anyway).

All very good and interesting points. To the fan issue first, can't you
reverse the direction the fan is turning by just reversing the two wires
going to it? Of course, if the pitch of the blades is wrong, that theory
won't work.
