I've been thinking of how to do a fan wall with computer fans - I need 250+cfm (factory spec) on the inside, and 500-800 cfm for the outdoor half. I think those numbers are going to be difficult to reach with computer fans.

The heat strips would be controlled by a relay, and controlled by the thermostat. they will be locked out most of the time.

the other option that would allow me to retain the factory fan in its entirety would be shutters between the fan blades and outdoor coil. I'm not sure how i would make an off the shelf unit fit - they're usually made in standard ductwork sizes. I see no downside to letting the fan freewheel for a few minutes at a time.
