3/4/5) CPU_FAN / SYS_FAN1 / SYS_FAN2 / PWR_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin (SYS_FAN1) and a 3-pin (SYS_FAN2)
system fan headers, and a 3-pin power fan header (PWR_FAN). 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.
CPU_FAN:
SYS_FAN:
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 conguration jumper blocks. Do not place a jumper cap on the
headers.

6) IDE (IDE Connector)
The IDE connector supports up to two IDE devices such as hard drives and optical drives. Before attaching
the IDE cable, locate the foolproof groove on the connector. If you wish to connect two IDE devices, remember
to set the jumpers and the cabling according to the role of the IDE devices (for example, master or slave).
(For information about conguring master/slave settings for the IDE devices, read the instructions from the
device manufacturers.)
