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.

4.5 Installation and handling of the LEDs
ItispossibletofreelypositiontheLEDlightingsuppliedinthecasetosuityoursystemsetupbyaxingand
connecting the adhesive strips. The LED strips must be connected to connector “E” on the PCB panel.
Description of the LEDs
The LED lighting included in the scope of delivery is controllable in several modes of color and operation.
Connector “D” on the PCB panel can be used to connect additional LED lighting strips up to a maximum of 24
watts for lighting the interior of the case. It is also possible to link the LED strips supplied directly together and
in this way extend them.
WARNING! Only 12V LEDs may be connected.
Inmanualmodebybrieypressingswitch“D”onthefrontpanelitispossibletocyclethroughthecolors.
When “breath mode” is enabled there is an intermediate step between each color.
1 White 8 Blue breath
2White breath 9 Orange
3 Red 10 Orange breath
4Red breath 11 Purple
5Green 12 Purple breath
6Green breath 13 Breath mode alternately in all colors
7 Blue 14 LEDso
Synchronized operation
To toggle between manual and synchronized operation hold down switch “D” on the front panel for about three
seconds.
In synchronized operation, connector “C” on the LED controller PCB is connected to the socket designated for
RGB LED on the motherboard. The integrated lighting is then controlled by the motherboard, with the same
range of colors.
For information about operation of the LED controller of your motherboard please refer to the motherboard
handbook.
4.6 Charging station for Qi enabled devices
The preinstalled charging station provides contactless charging of any device that conforms to the Qi standard.
If your device (e.g. your smartphone) is so equipped you can charge your device by simply placing it on area “I”
on the top of the case, without the need to plug it in.
In so doing, make sure you place the device so that its charge receptor is positioned centrally on charging
surface “I”.
