Hardware Installation
3/4) CPU_FAN/SYS_FAN (Fan Headers)
All fan headers on this motherboard are 3-pin. 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conguringmaster/slavesettingsfortheIDEdevices,readthe
