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. The default target temperature
is the Intel

Fan Speed Control (FSC) recommended value. This item

appears only when the CPU Q-Fan Control item is Enabled. Configuration
options: [35ºC] [38ºC] [41ºC] [44ºC] [47ºC] [50ºC] [53ºC] [56ºC] [59ºC]
[62ºC] [65ºC]

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.

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

The onboard hardware monitor automatically detects and displays the
power fan speed in rotations per minute (RPM). If the fan is not connected
to the power fan connector, 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.

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

’s PWM fan

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].
