4.4 Use of fan controller
The fan controller has two modes of operation.
1. Automatic operation
In this case the PWM signal of the motherboard is used and the speed of all PWM fans connected is automatically
regulated by the motherboard. To enable this the slider switch must be positioned at position “0” completely
to the left. For the automatic PWM fan controller to function, a cable must connect port “A” on the PCB panel
to the PWM connector on your motherboard. Lacking this connection it is only possible to regulate the speed
of the fans connected manually.
2. Manual control
Whenever the fan controller slider switch is moved rightwards away from its far left position, the PWM signal
is ignored and the speed of the fans is manually controlled in a stepless range. In total eight PWM fans can be
connected to the fan controller PCB. These eight sockets are divided into two channels (left and right) each
with four connections. By setting the switches “J” on the PCB it is possible to choose between Silence and
Performance modes independently for both of these channels. According to these switch positions the range
of fan speeds possible are 400 – 1,040rpm in Silence mode and 800 – 1,600rpm in Performance mode.
If the slider switch is returned to its starting position “0” on the far left, the PWM signal regains control of fans.
