4.4 FAN CONTROLLER
A

B
Channel 1
In total it is possible to connect six PWM fans to the fan controller PCB. These six connections are subdivided
into two channels (right and left) each with three connections. By operation of switch "H" on the PCB these
channels can be switched independently from one another between "Silence" and "Performance" modes. The
rate factors of the PWM fans connected here are determined as set out below according to the setting of the
front I/O fan switch.
Performance Mode
In combination with the Front I/O switch
50% | 800rpm* (Position 1)
70% | 1,120rpm* (Position 2)
100% | 1,600rpm* (Position 3)
*with SilentWings 3 1,600rpm
®
When the slider control is returned to its initial position of "AUTO" the PWM signal of the motherboard resumes
control of the fans.

Please note: To ensure proper functioning of the fan control and
the LED lighting, make sure that cable F is connected to the power
supply.

The fan controller has two modes of operation.
1. Automatic operation
In this mode the PWM signal of the motherboard is used and the
speeds of all PWM fans connected can be adjusted automatically
by the motherboard. The fan speed slider control must be set to its
initial position of "AUTO" in this case.
In order to use the automatic PWM control of the fans it is
B
necessary to connect the cable "A" of the PCB panel (4.3) with the
PWM connector of your motherboard. Lacking such a connection it
B
is only possible to manually control the speeds of fans connected.
2. Manual control
When the fan speed slider control is moved up from its initial
Channel 2
position of "AUTO" the PWM signal is ignored and the fan speed
can be manually set to one of three constant speeds.
