These fan connectors are used to connect cooling fans. The cooling fans will provide adequate
airflow throughout the chassis to prevent overheating the CPU and system board components.
BIOS Setting
Configure the cooling fans in the Advanced menu (“NCT6106D HW Monitor” > “Smart Fan Func-
tion” submenu) of the BIOS. Refer to the chapter 3 for more information.

Power Connector
Use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1. An
ATX12V power supply unit has a standard 24-pin ATX main power connector that must be in-
serted into the 24-pin connector. The 8-pin +12V power connector enables the delivery of more
+12VDC current to the processor’s Voltage Regulator Module (VRM).
The power connectors from the power supply unit are designed to fit the 24-pin and 8-pin con-
nectors in only one orientation. Make sure to find the proper orientation before plugging the
connectors.
The system board requires a minimum of 300 Watt power supply to operate. Your system con-
figuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the mini-
mum power requirement. To ensure that adequate power is provided, we strongly recommend
that the system is supplied with a minimum of 400 Watt power.

Important:
Insufficient power supplied to the system may result in instability or malfunction
of the add-in boards and peripherals. Calculating the system’s approximate power
usage is important to ensure that the power supply meets the system’s consump-
tion requirements.
