Creality Original Ender 3 Nozzle Fan DC BRUSHLESS PD04010MS4 DC 24V 0.10A Cooling Fan 40mmx40mmx10mm 4010 Sleeve Bearing for 3D Printer

Installation is about as you might expect...a lot of fiddly little screws...but not too bad. I bought these after I broke a fan blade trying to retrieve a stray piece of filament...I only needed the one, but I guess I now have a spare.

Comes in Creality packaging. Exactly what I needed to replace, fits perfect. Does not come with screws so you will need to use the current ones. Fit my ender 3 and ender 3 v2. Only thing difficult about install is running the wires through the cable sleeving.

Great deal, easy to use, and sturdy.
