CPU Q-Fan Mode [PWM]

Allows you to select the type of CPU fan cable connected to the CPU fan

connector. Set to [PWM] when using a 4-pin CPU fan cable. Set to [DC]

when using a 3-pin CPU fan cable. Configuration options: [PWM] [DC]

Some CPU fans with a 4-pin cable do not comply with Intel

specification. When using this type of CPU fan, you can not reduce the

CPU fan speed even if you set the CPU Q-Fan Mode to [PWM].

CPU Fan Ratio [Auto]

Allows you to select the appropriate CPU fan speed ratio for the system.

The default [Auto] automatically selects the fan speed ratio when

operating a low CPU temperature. Select a higher ratio if you installed

additional devices and the system requires more ventilation. This item

appears only when the CPU Q-Fan Control item is Enabled.

Configuration options: [Auto] [90%] [80%] [70%] [60%]

CPU Target Temperature [xxxºC]

Allows you to set the CPU temperature threshold when the CPU fan speed

is increased to lower the CPU temperature. This item appears only when

the CPU Q-Fan Control item is Enabled. The configuration options vary

depending on the CPU installed.

CPU Fan Speed [xxxxRPM] or [N/A]

The onboard hardware monitor automatically detects and displays the CPU

fan speed in rotations per minute (RPM). If the fan is not connected to the

motherboard, the field shows N/A.

Chassis Fan Speed [xxxxRPM] or [N/A]

The onboard hardware monitor automatically detects and displays the

chassis fan speed in rotations per minute (RPM). If the fan is not connected

to the chassis, the specific field shows N/A.

VCORE Voltage, 3.3V Voltage, 5V Voltage, 12V Voltage

The onboard hardware monitor automatically detects the voltage output

through the onboard voltage regulators.
