Review on πŸ”₯ GDSTIME 40mm Brushless Cooling Fan - High Performance 24V DC Fan, 40mm x 40mm x 20mm, 6000RPM by Mike Sutherland

Revainrating 2 out of 5

Quieter, but the remaining noise is high-pitched and annoying

I replaced the stock fan on my Ender 3 Pro 3D printer with this one. It makes less noise, but the sound it REALLY makes is an annoying high-pitched squeak. If you run it at less than 100% speed it makes an EXTRA whine, almost like a low speed signal or something. I would return it but since it already has a connector on the end and the cable isn't long enough to reach the processor I had to cut it off.
