PWM CONTROLLER MOUNT ASSEMBLY GUIDE
The Noctura fan we recommended in the 120mm Fan Mount build is compatible with a Pulse Width Modulation (PWM) controller (otherwise known as a fan speed controller) that allows you to adjust the fan speed. We made a simple mount that can be placed below the fan so that you can control it if you purchase this optional accessory.
Pulse Width Modulation Controller (Fan Speed Controller)
Place the PWM Controller through the printed faceplate before sliding on the corner piece. The PWM controller will be upside down due to the orientation of the wiring, but this will not affect the function of the device.
Align the mount with the the proper nut orientation and slide into place. Done!
