Just replaced the vent fan with a Vortex 2 fan which has 3 speeds forward and 2 speeds reverse. This was a fairly simple change out. 1) Had to drill out the rivets which held the old fan in. 2) Had to move the gear drive on the new fan to the alternate position, so I would be able to operate the vent lid. 3) I also rerouted the wiring, so I could get the new fan up into the vent hole.

New fan works fine, and I would consider it a real improvement over the factory installed fan.

Sounds like the "Up-grade Bug" might be getting ahold of someone! Congrats!
