[TR] re TR4 help, cooling fan, conclusion

[Bob Danielson]

Randall,
Just curious but if flipping the blade over has no impact, why does Hayden
have you flip the blade and swap the wires around to turn a pusher into a
puller? I know that swapping the wires changes the rotation of the fan motor
but there must also be something in the fan blade construction that makes it
more effective?  I learned the "hard" way when I went to change the fan from
puller to pusher and just flipped the blades over as the direction said to
do. The part about changing the wiring around was in a completely different
section of the instructions. As you said, just flipping the blades had no
impact of pusher vs. puller.

Don't mean to add insult to injury, Peter, but turning the blade over would
make no difference at all to airflow direction; just like a nut turns the
same way no matter which side goes on the bolt first.
