Silent, fast 3 Speed USB fan
Very silent and Low and Med speeds. Good airflow. Very high quality, well made product. Using this for my AVR located inside a narrow cabinet to improve coolng. USB cable is of sufficient length. Cons: The daisy chain USB female receptacle is exposed and sharp and could have caused scratches on my new AVR, so covered it with a piece of tape.
