WINSINN 40mm Blower Fan 24V, 3D Printer Micro 24 Volt Fans Blower 4020 Dual Ball Bearing, Brushless Cooling 40mmx20mm 2PIN (Pack of 2Pcs)

The blower fan in the case of my CR-10S Pro V2 was starting to die after all these years and made a terrible grinding noise. It is the same fan as the part cooling blower except for the end connection. There is a clip on the hotend blower and not on the case fan. I bought this to fix that issue. It runs quieter than the previous fan with a small decrease in airflow. I definitely recommend it as a replacement for the case fans.

This blows significantly more air than the 4015's I usually use. They have a smaller footprint overall but a larger opening and move a LOT of air. They're noisy at 100% speed but if you need to cool something, this is the fan to use.

I had to replace the part cooling fan on my CR 10S Pro because the Creality fan solder joint failed. I purchased these fans and designed a shroud to fit on a Bond Tech DDX extruder (photos included). There is a connector on the end of the cable, but not long enough to go to the breakout board. Therefore, I had to splice the wire. I would have preferred just mounting and plugging in (4 stars)

It's pretty hard to find fans at this voltage and size that have ball bearings instead of sleeves. It makes them so much quieter. Airflow seems decent for a blower fan, too.

fan works great and produce a lot of flow for its sizes

Used on 3D printer.

good airflow just louder than I expected. normally, I find blower fans have a more appealing sound (and sound level) but, these are just noisy to me.

Does exactly what you need. I replaced my board fan and this fits and works like a charm. I suggest testing the pin assignment in the connector. I had to switch mine.
