See picture below. Do these fridge fans really work to help keep the fridge cool? They might be an inexpensive fix to help my fridge stay cool in this heat if so.
I’ve used one before. I’m not sure if they actually lower the internal temperature of the fridge, but they do move the cold air around, evenly distributing it throughout the fridge, which is helpful. So, they do in effect keep your items in your fridge better cooled.
