2pcs 5015 Blower Cooling Fan, 50mm x 50mm x 15mm Ball Bearing Cooling Fan with 2 Pin Terminal for 3D Printer Hotend Extruder Heatsinks(24V 0.17A)

I'm not here to dispute what others have said, just my own experience.I am trying to use these fan as a part cooling fan on my modified Ender 3 using an SKR v1.3 board. One came with disconnected leads. Considering trying to resolder them.The other one did not work. I plugged it into the FAN socket on the SKR V1.3, and it never started up, it did not matter whether it was part of a print, or just sending the M106 command. Plugged it into the 24v socket, and it still didn't power up, even though my board cooling fan works just fine from that.

These were cheap and are performing as such. they don't operate well and make a ton of noise. If they weren't so cheap, I'd be returning them.

Fan blower too weak, caused bad 3D prints. Go with better brand.

They work fine but vibrate a lot and are noisy but they are cheep

This fan was a perfect fit and operated normally in the small globe humidifier.

Neither fan worked!

I dont recommend this fan coolers. Despite I've read the others reviews I took the risk and bought, but it was a very bad election. Please dont buy this.

Good
