Review: Small but does the job - A great little fan for keeping your systems cool and not overheating. Just plugs into a USB port on your system, and it powers up when the system turns on (I'm using on a PS3). Slight noise from such a small thing, but it's nothing too overly annoying. Definitely a worth buy.
Review: Works all day and keeps my Linux computer cool. - I use this with a mini Linux-based computer (about 4"x4"x1/2". I used a very small piece of double-sided tape to attach it to the hottest section of the computer. I did not cover any computer cooling fins. The fan immediately brought down the temperature and continued to do so all day and night. It does make some noise, but it is no big deal. And if the fan ever gives out, I have three more as backups!

### ⭐⭐⭐⭐ Pretty satisfied
*by G***O on September 16, 2022*

All I needed were small fans that ran off of USB in order to add a cooling option to the inside of a costume. These were exactly what I was looking for, so I'm happy. They have a very quiet buzz that only really affects me because the fans will be close my face, but it's not too bad of a sound so I'm not really bothered. They also aren't very powerful, but I wasn't expecting much out of a tiny 5V fan, and it works well enough at close range. I also noticed some other reviews saying that there were some exposed wires on the units, but it seems they are a bit more contained on the ones I got so I am not too worried about that. Overall, pretty satisfied.
