Nesteq's FanMax fan controller is an ideal device to control and adjust the speed of your PC's cooling fans. The FanMax uses Cooling Zones that allow up to four fans to be turned on/off at the touch of a button. This gives quick and simple control over the airflow / noise balance. The voltage going to each connected fan, depending on your settings and requirements, can be precisely adjusted from 6 to 12 volts. Whether you want high or low fan speed or somewhere in between, the FanMax can control each fan independently for greater flexibility. FanMax comes with all necessary cables to connect up to 8 fans with either 3-pin (standard) or 4-pin (PWM) connectors. All you need is an unused 5 (optical drive) bay and then you are ready to go.
