I got myself 4 of this fan for my case, since the original have given up the ghost. Even if Enermax expensive than the average, the price is justified. Here you can get in addition to fan anti-vibration mounts, a 4 pin Molex adapter and tape for the light switch. The fan speed can be pre-set before the motor, I do that via PWM connectors on the mainboard. The LEDs still shine bright even at 40% capacity and by the reflective blades, it looks really good. In addition, the fans are quiet and torquey, as you will notice when Davor holding his hand. All in all a top product that is worth the money!
