Air flow for residential fridge

I installed a Samsung over two years ago. It is in a slideout, and I sealed and insulated both vents. It gets its ventilation through a 3/4 inch gap at the sides and top. For good measure, I installed one of the 12 volt fans from the original Norcold installation in the bottom side of the wooden fridge enclosure, and wired it through a cheap thermostat so the fan comes on when the temperature behind the fridge exceeds 90 degrees. The fan pulls interior air into the fridge enclosure and pushes heated air out through the gaps. No problems since we installed it.
