I have to admit this fan looks cool, and it delivers great airflow. It's noise is quiet on it's own, but once I installed it in my case, it was as though it was blowing against it too hard and creating an extremely loud noise. (Yes I did install it properly). So I had to leave this fan out of my computer as I couldn't put up with the noise. Can't complain though, it was my choice of fan. Bad luck!
