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

•
Be sure to connect fan cables to the fan headers to prevent your CPU and system from over-
heating. 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.
5) FDD (Floppy Disk Drive Connector)
This connector is used to connect a floppy disk drive. The types of floppy disk drives supported are:
360 KB, 720 KB, 1.2 MB, 1.44 MB, and 2.88 MB. Before connecting a floppy disk drive, be sure to locate
pin 1 of the connector and the floppy disk drive cable. The pin 1 of the cable is typically designated by
a stripe of different color. For purchasing the optional floppy disk drive cable, please contact the local
dealer.
