Good suggestions all. I added a fan using the light switch contacts and it worked fine. The thermistor wire chase is a great idea. I've heard of using the condensate drain too, and hence my caution. Sure we don't want to plug it with additional wire. But... Some condensate drains have a bend in them that's meant to create a water "trap." What the trap does is prevent loss of cold air down the drain. Counterintuitive but apparently critical, so I take it seriously. So if you put a wire up there, please preserve what otherwise looks like a kink.
If not a loop, then they use a small plastic insert in the end of the tube that blocks almost all of the opening...this is an important bit of knowledge....either the loop or the plastic outlet piece.
If it was me, I would use thermistor fans that are temperature controlled for the exterior fans and just let the inside the fridge fan run constantly...do you really want to be adjusting fan speeds all day?
