Review on 🖥️ Wathai 3Pin 12V 92mm 92x25mm DC Brushless Cooling Fan for Computer Case: Enhance Your PC's Performance! by Briceston Criss

These fans were much cheaper than factory installed fans and they also have a bearing instead of a bushing. I was a bit concerned about the slightly higher DB noise rating for the stock type compared to the same size in the sleeved version. When installed, they are very quiet. As a longtime RV technician, I've heard fans a lot louder, and since they're double-bearing, they should run for many hours. They are used to increase airflow through the top cooling fins on the Norcolds 1200 series.
