3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 3-pin CPU fan header (CPU_FAN) and a 3-pin (SYS_FAN) system fan header.
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.
5) IDE (IDE Connector)
The IDE connector supports up to two IDE devices such as hard drives and optical drives. Before attach-
ing 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 configuring master/slave settings for the IDE devices, read the
instructions from the device manufacturers.)
