RV Refrigerator Fan Noise Fix!

I believe this issue is mainly related to RVs that have the refrigerator in the slide out. Instead of a roof vent it has a side vent and it has trouble with air flow. The main reason I made this change was to reduce the fan noise and not to improve cooling. Here is the link for the fans I purchased. I purchased two! https://www.ebay.com/itm/Dometic-Refr... Also, I just noticed the ebay seller has another fan kit that might even be better than this solution for airflow. I might add these at a later date if I have cooling trouble. https://www.ebay.com/itm/2-RV-DOMETIC...
