Hardware Installation
•
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.
4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3/SYS_FAN4 (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), three 4-pin (SYS_FAN1~SYS_FAN3) and a
3-pin (SYS_FAN4) 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 motherboard supports CPU fan speed control, which requires the use of a CPU fan with
fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed
inside the chassis.
