6) CPU_OPT (CPU Fan/Water Cooling Pump Header)
The fan/pump header is 4-pin and possesses a foolproof insertion design. Most fan headers possess a
foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation
(the black connector wire is the ground wire). The speed control function requires the use of a fan with fan
speed control design.

7) D_LED1/D_LED2 (Addressable LED Strip Headers)
The headers can be used to connect a standard 5050 addressable LED strip, with maximum power rating
of 5A (5V) and maximum number of 1000 LEDs.
Connect your addressable LED strip to the header. The power pin (marked
with a triangle on the plug) of the LED strip must be connected to Pin 1 of
the addressable LED strip header. Incorrect connection may lead to the
damage of the LED strip.
