Fan attached in addition to a Master Hyper TX3 cooler. 4 screws provided with the fan higher quality compared to other fan screws that I could handle. An adapter is supplied with allows to extend at first the son, to have a molex plug that can be connected directly to the power supply (if there is more than possible connection on the motherboard), a socket 4 femmelle pins, and a 3-position switch for varying the speed. Does his job properly, and without noise. To see in the time, but the Antec products exude quality.
