GIGA-BYTE TECHNOLOGY GA-Z270X-Gaming K5 User Manual

5) SYS_FAN3_PUMP (System Fan/Water Cooling Pump Header)
The fan/pump header is 4-pin and possesses a foolproof insertion design. 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.Theheaderalsoprovidesspeedcontrolforawatercoolingpump,refertoChapter2,"BIOSSetup,"

6) CPU_OPT (Water Cooling CPU Fan Header)
The fan header is 4-pin and possesses a foolproof insertion design. 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.

andtheotherendtoyourRGB(RGBW)LEDstrip.Theblackwire(marked
with a triangle on the plug) of the extension cable must be connected to Pin
1 (12V) of this header. The 12V pin (marked with an arrow) on the other end
of the extension cable must be lined up with the 12V of the LED strip. Be
careful with the connection orientation of the LED strip; incorrect connection
may lead to the damage of the LED strip.
