4/5) 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.
3) OC_PEG (PCIe Power Connector)
The power connector provide auxiliary power to the onboard PCI Express x16 slots. When two or more
graphics cards are installed, we recommend that you connect the power cable from the power supply to
the ATX4P connector to ensure system stability.
