Refrigerator Cabinet Cooling Fan

[salivan]

Adding a 12v computer fan to exhust air flow OUT of the fridge cabinet sounds like the way to go? My question is: what set-up do you use to turn the fan on/off? Just when the fridge runs (which should be an easy tap into the fridge hot wire) or manual, or on a timer, or ?????

I have a small thermostat at the rear of the fridge. This swich on/off the circuit of two fans.
One small (60mm diameter) at the heat exchanger of the fridge and one bigger (120mm diameter) i built in the wall between fridge and gaucho. He blows the air behind the gaucho. The thermostat opens at about 100F. The fan´s just work after turn the fridge on inside with the internal switch. In case it is off -for longer no use periode- the fan´s will not work also if the fridge is connected to the batterie
I took an old speaker bezel on the outside.

Wanted to keep it simple so just tapped the hot and ground wires to the fridge fan.
