I can't fairly review this because I never figured out how to install it properly. My guess is, some kind of nuts are required, but those didn't come packaged with the fan so I'm at a loss. I'll give it three stars because it functioned fine when plugged in, but the lack of documentation is not good. Any help on this would be appreciated, in fact.

Cheap, pretty loud at full speed fan, but it moves a good amount of air.

Can have some bearing noise that will annoy people like me.

Works well, little loud for me. Definitely does a lot better job at airflow than what the fans that came with my case did.
