This a nice fan. It is quite yet delivers a good amount of air. The only down side that I had was all the wires are black and no pinouts were given for the connector. I did send a text to the Coolerguys and they responded quickly with the pinout information. Great customer service. I'll be buying more of these fans soon. I am installing them in my hood vents on my Jeep Jk to help draw the heat out of the engine bay.
