Gigabyte GA-M68MT-D3P, GA-M68MT-S2P user manual CPUFAN/SYSFAN Fan Headers, LPT Parallel Port Header

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)LPT (Parallel Port Header)

The LPT header can provide one parallel port via an optional LPT port cable. For purchasing the optional LPT port cable, please contact the local dealer.
