Review on 💨 High Airflow 140mm x 38mm 12V Powerful Fan - Optimized for Power Mining, Workstation & Server Cooling by Steve Walton

I have a Seasonic PSU for my FreeBSD server. The fan in the PSU seemed to be some kind of sleeve bearing that was worn out because it was starting to make a knocking noise. I decided that replacing the fan is cheaper than the entire PSU, so I bought this fan. Works perfectly. In fact, it looks almost identical - for example, the shape and number of blades are exactly the same. I don't notice any noise to speak of, and if it really is a ball bearing fan (didn't really test it before installing it) as advertised, it really is great value for money. Thumbs up.
