Hardware Monitor

CPU/MB Temperature [xxxºC/xxxºF]

The onboard hardware monitor automatically detects and displays the motherboard and CPU

temperatures. Select [Ignored] if you do not wish to display the detected temperatures.

CPU Fan / Chassis Fan 1 / Chassis Fan 2 Speed [xxxxRPM] or [Ignored]

The onboard hardware monitor automatically detects and displays the CPU, chassis, and

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

the field shows

N/A

. Select [Ignored] if you do not wish to display the detected speed.

VCORE / 3.3V / 5V / 12V Voltage

The onboard hardware monitor automatically detects the voltage output through the onboard

voltage regulators. Select

Ignored

if you do not wish to display the detected voltage output.

CPU Q-Fan Function [Disabled]

Allows you to enable or disable the CPU Q-Fan feature that smartly adjusts the fan speeds

for more efficient system operation. Configuration options: [Disabled] [Enabled]

Select Fan Type: [PWM Fan]

This item appears only when you set the

CPU Q-Fan Function

item to [Enabled] and allows

you to select the CPU fan type you installed on the motherboard.

Configuration options: [PWM Fan] [DC Fan]

•

If you install a PWM (4-pin) fan but set this item to [DC Fan], the fan you installed may

not work.

•

If you install a DC (3-pin) fan but set this item to [PWM Fan], the CPU Q-Fan function

will not work, and the fan you install will always run at full speed.

CPU Q-Fan Mode [Silent]

Allows you to set the appropriate performance level of the CPU Q-Fan. When set to

[Optimal], the CPU fan automatically adjusts depending on the CPU temperature. Set this

item to [Silent] to minimize fan speed for quiet CPU fan operation, or [Performance] to

achieve the maximum CPU fan speed. Configuration options: [Performance] [Optimal] [Silent]

Chassis Q-Fan Function [Disabled]

Allows you to enable or disable the chassis Q-Fan feature that smartly adjusts the fan speeds

for more efficient system operation. Configuration options: [Disabled] [Enabled]

Chassis Q-Fan Mode [Silent]

Allows you to set the appropriate performance level of the Chassis Q-Fan. When set to [Optimal],

the Chassis fan automatically adjusts depending on the Chassis temperature. Set this item to

[Silent] to minimize fan speed for quiet Chassis fan operation, or [Performance] to achieve the

maximum Chassis fan speed. Configuration options: [Performance] [Optimal] [Silent]
