This fan is great, it allows me to stay productive when the temperature gets too heavy! It is very noisy, broken down exactly what is needed: neither too much nor too little. The finish is at the rendezvous: we do not buy poor quality, even with this very attractive price.
Only downside for those that do not have USB port on the side: the axis is too short to be connected behind the screen. It will consider a support in this case.
