2pcs 5015 3D Printer DC Brushless Blower Cooling Fan for RepRap i3 CR-10 and Other Small Appliances Series Repair Replacement (24V)

Works great to push the mist from the humidifier, it is extremely quiet and was a drop-in replacement. Plugged it in and it worked like a charm!

Very good and accurate product, does what it’s supposed to do!

The wires are very short and don't reach the board on a creality cr10v2. Plugged fan into board to make sure it was working it immediately started smoking and died.

These are a good replacement fan and great price

only one of the two has continued to work after a week of use. one of them died and was useless.

I put one of these on my Ender 3 and it works great. But you do have to switch the wires going into the connector. To do that, just use something sharp like tweezers, press the metal tab that you can see, and pull the wire out at the same time. Then switch them around. They should just push back in.These fans are not "wired backwards", per se. Their red wire really is the positive lead and the black one really is the negative lead. But the connector on 3D printers is backwards from the connector on things like humidifiers. I took one star off because the seller claims they are for 3D printers but you still have to do this.You also have to extend the wires or use an extension. I just clipped the wires in the middle and soldered an extra 3 feet of red and black wire there.It is very quiet and gives great airflow. I think it is even quieter than the original parts fan on the Ender 3.I think all of the people saying that these don't work at all did not know to switch the connector.

Does what fans do!

It's quiet but not enough cooling for my prints
