Mark Wilson I purchased some of these in 2021 and they're still working as they were when I got them.
I removed the feet from the fans and then wire tied the two fans facing up to two old Roku streaming boxes for legs. My PC's behind my monitor so I wanted to pull the hot air from both and send it upward. It has worked perfectly and medium speed is all that's needed.
Keeping the, or any fans clean is essential, especially when they're for electronics.
I'm setting up another PC and plan on purchasing another set. It fits well with our furniture setup.
