AC Infinity MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified for Receiver DVR Playstation Xbox Computer Cabinet Cooling

Connected those to the TV usb output, one under the Android media box, and the other on top on a NUC (removed NUC top cover), it is so effective it brought NUC temperature during heavy tasks from 72c to 46c while remain silent. Highly recommended. (note the dual fan connection cable comes with a female usb provision for connecting another set of fan/fans)

Great product. A must have for custom home cinema

Airflow is weak

Silent and convenient. Using them to keep my amplifiers cool in the cabinet.

I bought these to cool my amplifier down in the summer time. Works perfectly. No wind noise from them at all! And they do a good job. Buy buy buy if you have a over heating problem in your amplifier. The only negative things are that the cord is quite stiff. And long. Otherwise perfect.

Very efficient and quality product

寝室にあるルーターを冷やすのに使っています。 存在を忘れるくらい静かで、私は気になりません。 ルーターもしっかり冷えます。 買って良かったです。

working well for about 6 months now. very quiet. use it to remove hot air from AV system. only crib is that the wire is kind of thick and long. it may be a blessing for others who need to run the wire longer. I use a dedicated usb power supply (1mA) to power it. dont want to load the USB port of my receiver all the time.

Very happy with my purchase, those fans work great and are easy to clean!
