The fan is there to help with efficiency. The coils don't always get the airflow they need, especially for people that open the refer door and and stand and look for 5 minutes thinking about what they want. Then there are the people that open the door, grab a drink, and leave the door open while they drink half of it. These refers aren't efficient, but they are light, and they work. Don't blame Forrest River, every RV maker uses them.
Now you can put in a "house" style refer, with compressor, and motor, and all the extra weight, but then you loose the option to operate on propane while traveling or dry camping, then you would need the cooler full of ice, and a place to get more ice.
