RV Refrigerator air circulation fan, do they help?

Does anyone have experience with fridge fans? I am wondering does it help with cooling and does it help to get the fridge cooler faster? I am looking at getting one of these bad boys…

I use that very same fan. It doesn’t get the refrigerator cooler faster but does help circulate the cool air.

I never found them to help in the heat. I did upgrade to one of these and it has been fantastic!

@ExtraStout can you hear it running with those fans?
