### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good fans for a good price
  

*by A***R on Reviewed in the United States on August 28, 2024*

Good quality fans that really help keep temps down. Good air flow and fit perfectly. Not the quietest fan I’ve ever heard but great value for the money!

    Mine worked
  

*by A***N on Reviewed in the United States on April 6, 2021*

Both of mine worked. I replaced a 4010 with the 4020... They're loud. But they do the job. Def not a fan you'd want on a printer in your bedroom.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Worked fine for 500 hours, then suddenly died (SEE UPDATE)
  

*by F***Y on Reviewed in the United States on December 29, 2023*

I bought these 4020 dual ball bearing fans to upgrade my 3D printer with bigger fans that would also be quieter than the stock ones. These fans did just that. They are much quieter than the 4010 fans that my printer was using before and also can move more air than before. The fit is pretty good through I wish the wire lead was a bit longer.The problems I have with this fan are that it has a lot of vibration and that one of them has suddenly died after only 500 hours. On the noise side of things, there is the obvious "woosh" of the air it moves and a slight high-pitched whine as the RPM increases, but the vibrations both fans give out lead me to believe that the center fan section is either not balanced properly or that there is too much play in the bearings. As for one of the fans suddenly dying after only 500 hours, that is my biggest complaint. The other fan seems to be working as expected after the same 500 hours of use. Neither one showed signs of pre-mature bearing failure.UPDATE!Turns out it was just the wire that failed, not the fan itself! I ended up removing the old wire and soldered in a new silicone wire pair. Now it is back to working like it should! I've since constrained the wire a bit better in hopes that the movement and vibrations of the print head don't cause it to fail again.As for the one fan that has been cooling the main board, that fan still functions just fine!Upgraded the rating to 4 stars! -1 star because of both the wire failure and the fact that both fans vibrate enough at 80%+ speed that it can be heard over the normal "woosh" sound of the air moving. Under that speed, the vibrations are not very noticeable.
