Review on Spal 30103009 4'' Paddle Blade Pusher Fan: Efficient Cooling Solution for Various Applications by Omar Austin

Great little fan. I use two of these in the back of my RV fridge. I use the speed controller to slow them down. I've had mine for a year now with no problems with occasional use. https://www.amazon.com/RioRand-7-80V-Motor-Controller-Switch/dp/B071NQ5G71/ref=mp_s_a_1_2?keywords=12+volt+speed+controller&qid=1563120143&s=gateway&sprefix=12+vilt+speed+ controller&sr =8-2
