fan extension card, please refer to the To install Fan Extension Card section in this

inside the system may damage the motherboard components. These are not jumpers!
Do not place jumper caps on the fan connectors!

• Connect the pump cable from the all-in-one cooler (AIO cooler) to the AIO_PUMP
header, and connect the fan cables to the CPU_FAN and/or CPU_OPT header(s).
