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

The onboard hardware monitor automatically detects the voltage output through

the onboard voltage regulators.

CPU Fan Ratio [AUTO]

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

defaault [Auto] automatically selects the fan speed ratio when operating a low

CPU temperaturue. Select a higher ratio if you installed additional devices

and the system requires more ventilation. Conﬁguration options: [Auto] [90%]

[80%] [70%] [60%] [50%] [40%] [30%] [20%]

CPU Target Temperature [xxºC]

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. Configuration options: [35ºC] [38ºC] [41ºC] [44ºC] [47ºC] [50ºC]

[53ºC] [56ºC] [59ºC] [62ºC] [65ºC]

Chassis Fan Speed [xxxxRPM] or [N/A] ([Ingnored] [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.

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

ʻs 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].
