3/4) CPU_FAN/SYS_FAN1/2 (Fan Headers)
All fan headers on this motherboard are 4-pin. 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. For
_
optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.

• Be sure to connect fan cables to the fan headers to prevent your CPU and system from
overheating. Overheating may result in damage to the CPU or the system may hang.
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.
5) LED_C (RGB LED Strip Header)
The header 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 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.
