3/4) CPU_FAN/SYS_FAN1/SYS_FAN2 (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.

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.
