3/4) CPU_FAN/SYS_FAN1/2/3 (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 over-
heating. Overheating may result in damage to the CPU or the system may hang.

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.
