this fan has a good efficiency. All cooling fans have different ratings in terms of the air flow per minute and their respective current rating. This is not the most powerful fan out there. But for a rate of current used at 12v, this fan gives the best air flow per minute. My more powerful fan uses twice as much current and twice as much air flow - whence the same efficiency.

Fan is working right. Can be used over wide voltage range. Will start rotating with about 5V and you can increase voltage (and speed) up to nominal 12V. So if you want to adjust air volume you can just adjust voltage and have proper cooling. Will fit many small projects, DIY and so on.
