GDSTIME40mm Brushless Cooling Fan, 40mm x 40mm x 20mm 24V DC Fan 2Pin 6000RPM for 3D Printer 2-Pack

Glad it was the same mounting size. Also comes with 2 fans and hardware instead of 1 as advertised. Noice level is close to stock. Good deal all the way around.This is a good upgrade as it has more cfm / air flow. than the stock fan does. Not 100% sure it fit in stock Creality housing.I’m using a custom air duct but has exact ender mounting size. Helped with a heat creep issue I had with gcr hotend. Hop this helps!

This fan is a replacement for one of my Ender 3 Max Neo hotend fans. It is just a hair louder but the noise is from the air movement, no high pitch whine or other motor noises. It might move too much air as the deflected air moves down the print nozzle which could be an issue if you print with ABS or ASA. I have a modified hotend shroud so the 4020 fits with no issues, I have not tried with the factory shroud but from just eyeballing it I think there will be no issues. I will buy again

Worked perfect for my new hot end duct build. The fan is so much more quite than the stock on and works as it should. No issues or hiccups with it

This fan is an exactly what I was looking for to upgrade cooling on my ender 3. The fan moves considerably more air than the stock fan at a comparable noise level, it is much quieter than other 4020 fans I tested from Amazon. And doesn't require any modifications to run on an ender like a noctura fan would.

It's a fan. It's not as quiet as a Noctua, but you knew that. Quality seems fine.

The stock Ender 3 fan wouldn't allow printing with PLA after converting my hotend to an all-metal option. Once this fan was installed, the clogs from heat creep stopped. Best of all, it's no louder than the stock fan!

I had a hotend cooling fan go bad on my 3D printer, and I wanted to upgrade it (My printer uses the same fan for hotend and part cooling, so more airflow is always better), and grabbed one of these.Not much to say, really... It fit in the same spot (Although it is much thicker than a "Generic" 40MM fan so it may not work for some printers), worked when I plugged it in, and although it is a little more noisy, it moves a LOT more air. Only real complaint was I wish the wires were longer. Would have been nice to just wire it right up to the control board, but instead I had to solder and heat-shrink them together by the hotend.Biggest problem I could see someone else having is either the fan not fitting in a smaller hotend like the one on the Ender 3, or accidentally buying this 24V fan for their 12V printer, in which case it would still work, but not move much air at all and may cause printing problems. Double-check your voltages!

Solid upgrade over the stocker hotend fan on my Ender 3 NEO. Just be sure the red/black wires are oriented the same during install.
