Review on 🌀 ANVISION 40mm x 10mm DC 5V USB Brushless Cooling Fan, Dual Ball Bearing, Improved YDM4010B05 by Michael Lightfoot

noctua. I measured the decibels of this fan compared to the stock Ender 3 fan and found it to be about 5 decibels quieter on average (measured at 1 inch and 1 meter). All in all, a good buy if your stock Ender 3 fan broke and you want to buy this - something a little quieter, with the same airflow, and replace it outright. I also bought a 40mm Orion fan, which is also 24V and much quieter than the Anivision fan, although it has a smaller CFM, uses different screws and doesn't have a 2-pin connector.
