6) SYS_FAN3_PUMP (System Fan/Water Cooling Pump Header)
The fan/pump 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. 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," "M.I.T.," for more information

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.
