Determine the HD audio pin connectors on your motherboard and insert
the HD audio cables into the sockets allocated there.
USB 2.0
Locate the USB 2.0 pin connector on your motherboard and attach the
USB 2.0 cables using the designated sockets there.
USB 3.0
Locate the USB 3.0 pin connector on your motherboard and attach the

4.4 FAN CONTROLLER
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 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 necessary to connect the cable "D" of the PCB
panel (4.3) with the PWM connector of your motherboard. Lacking such a connection it 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 position of "AUTO" the PWM
signal is ignored and the fan speed can be manually set to one of three constant speeds.
In total it is possible to connect six fans to the fan controller.
