6) 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.
7) LED_CON2 (Heatsink LED Power Connector)
The power connector provides power to the LEDs on the Chipset heatsink.
8) SATA_EXPRESS (SATA Express Connector)
The SATA Express connector supports a single SATA Express device.
M2_20G and SATA Express connectors can only be used one at a time. The SATA Express
connector becomes unavailable when an M.2 SSD is installed, but the SATA3 4/5 connectors
are still functional.
