Review on NTE Electronics 77-4010D24 High Performance Bearing Thermal by Mark Greenwood

I used this to replace the stock fan on my Creality Ender 3 because the original fan died and the fan blades hit the case. This fan pushes a lot of air - much more than a standard fan. So in that respect he's good. However, it is noisy. High pitched screeching, very annoying when you are in the same room, LOUD. I recently added dampeners to my stepper motors to reduce noise and make sitting next to the 3D printer more bearable. This fan pretty much cut the work I was doing there. I'll leave it in place until I find something quieter. The printer is in my office and I have to work, so having something quieter is very valuable.
