Small, Discrete, and Powerful

What a great product! I bought this to go into a cupboard which houses my TV One Connect Box, a Chromecast Ultra (which produces a lot of heat) and a modem. I've tried other fans in there but nothing as good as this little beauty. I love the fact that I can control the speed and that you can daisy chain these. Thinking about getting other one for my PS4 that sits in the cupboard next to this one. Super quiet too. For something sooo small.... this is my greatest fan.

Good Result

This Infinity mini fan is really effective in cooling our Cambridge CXR200 amp. I was always concerned with how hot it got after being in use for long periods of time. Now with the mini fan running on it’s lowest speed setting the amp barely gets warm. Good result. Highly recommended. Thank you. Roy.
