Fan Headers; Water Cooling Cpu Fan Header - Gigabyte GA-Z87MX-D3H User Manual

3/4) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3 (Fan Headers)
All fan headers on this motherboard are 4-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 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) CPU_OPT (Water Cooling CPU Fan Header)
The fan header is 4-pin and possesses 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.
• 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.
