• 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.
3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 3-pin CPU fan header (CPU_FAN) and a 4-pin system fan header (SYS_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.

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.)
