Hardware Installation
•
Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheat-
ing. 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_FAN1/2/3/4/5/6/7 (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), five 4-pin (SYS_FAN1/SYS_FAN2/SYS_FAN3/
SYS_FAN4/SYS_FAN5) and two 3-pin (SYS_FAN6/SYS_FAN7) 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.
