• 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 conguration jumper blocks. Do not place a jumper cap on the headers.
4/5)CPU_FAN/SYS_FAN1/2/3/4/5/6(FanHeaders)
The motherboard has a 4-pin CPU fan header (CPU_FAN), four 4-pin (SYS_FAN1/SYS_FAN2/SYS_FAN3/
SYS_FAN4) and two 3-pin (SYS_FAN5/SYS_FAN6) system fan headers. 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(PCIePowerConnector)
The power connector provides auxiliary power to the onboard PCI Express x16 slots. When two or more
graphics cards are installed, we recommend that you connect the 2x3 power cable from the power supply
to this connector to ensure system stability.
