### ⭐ 1.0 out of 5 stars







  
  
    These fans are junk!
  

*by A***E on Reviewed in the United States on November 26, 2023*

I was running 8 of them. After about two weeks several fans developed what sounds like bad bearings. They screech and groan. Replaced and same happened with more units. Good fans this size from legitimate electronics vendors cost on average 5$ each. Now I know why!
