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) LED_C1/LED_C2 (RGB LED Strip Headers)
The headers can be used to connect a standard 5050 RGB LED strip (12V/G/R/B), with maximum power
rating of 2A (12V) and maximum length of 2m.
Connect your RGB 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 (12V) of
this header. Incorrect connection may lead to the damage of the LED strip.
For how to turn on/off the lights of the LED strip, please navigate to the "Unique Features" page
of GIGABYTE's website.
Before installing or removing the devices, be sure to turn off the devices and your computer. Unplug
the power cord from the power outlet to prevent damage to the devices.
