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

Easy replacement, works perfectly, no electrical knowledge required for install.

After 2 years of owning my ender 3 the cooling fan started to get very loud. These fans were a perfect cheap replacement. Better yet they were an exact match to the original design so they fit my 3d printed bullseye fan duct without having to modify anything. Best part is it's a 2 pack so next time it starts getting loud again I already have a replacement. My printer runs nearly 24/7 and the 1st fan has held up very well nice and quiet for many months. I'd say they are on par quality wise as the original that came with the printer and should last as long before getting loud again. So I have zero complaints good fans at a good price a++.

Perfect replacement fan for my engraver

But it's only long enough because it comes with an extension clip, which puts a little awkward bulge in your cable wrap.

I found that my hotend fans went out fairly frequently because of dust buildup. Swapping it in was easy aside from soldering, but nothing is saying that you can't use crimp connectors. I think that'd be the better option if you're finding that you have needed to replace the fan more than once. The wires are long enough to decide where you want to splice in; I suggest somewhere up inside the loom. Just make sure you put them in the orientation as the original! It's nice to have a spare on hand.
