A bit noisy at 12v, but works fine at 7v. Since I've got a pretty entry level system, it's enough to draw fresh air in and help cool the CPU, GPU and storage.

I got rid of two of my old fans that I don't use from a 4 pack.

It was a left over from my previous build, definitely good addition to the top of my PC. Quiet as a whistle.

Cheap but effective. If you just need a little extra airflow and don't care how it looks, it's hard to beat a four-pack of these.
