Does your refrigerator work well or not so good?

I don't understand the video. Computer fans are designed to be durable, quiet and run on very little electricity. My camper did not have any fans for the refrigerator compartment so I installed two computer fans. I turn them on with a switch only for hot days when the extra cooling helps. There is very little noise even though mine are in the camper a couple of feet from where I sit. The little bit of noise they make helps me to remember to turn them off when not needed.
