& CPU Vcore/Dram Voltage/+3.3V/+5V/+12V
Displays the current system voltages.
& CPU/System Temperature
Displays current CPU/system temperature.
& CPU/System/Power Fan Speed
Displays current CPU/system/power fan speed.
& CPU Warning Temperature
Sets the warning threshold for CPU temperature. When CPU temperature exceeds the threshold, BIOS
willemitwarningsound.Optionsare:Disabled(default),60

& CPU/System/Power Fan Fail Warning
Allows the system to emit warning sound if the fan is not connected or fails. Check the fan condition or fan
connectionwhenthisoccurs.(Default:Disabled)
& CPU Fan Control Mode
Auto Lets the BIOS automatically detect the type of CPU fan installed and sets the optimal CPU
fancontrolmode.(Default)
Voltage Sets Voltage mode for a 3-pin CPU fan.
PWM Sets PWM mode for a 4-pin CPU fan.
& CPU Fan Speed Control (CPU_FAN Connector)
Allows you to determine whether to enable the CPU fan speed control function and adjust the fan speed.
Normal Allows the CPU fan to run at different speeds according to the CPU temperature. You can
adjust the fan speed with EasyTune based on your system requirements.(Default)
Silent Allows the CPU fan to run at slow speeds.
Manual Allows you to control the CPU fan speed under the Slope PWM item.
Disabled Allows the CPU fan to run at full speeds.
& Slope PWM
 AllowsyoutocontroltheCPUfanspeed.ThisitemiscongurableonlywhenCPU Fan Speed Control is
set to Manual. Options are: 0.75 PWM value /

& 1st System Fan Speed Control (SYS_FAN1 Connector)
Allows you to determine whether to enable the system fan speed control function for the system fan
connected to the SYS_FAN1 connector and adjust the fan speed.
Normal Allows the system fan to run at different speeds according to the system temperature. You
canadjustthefanspeedwithEasyTunebasedonyoursystemrequirements.(Default)
Silent Allows the system fan to run at slow speeds.
Manual Allows you to control the system fan speed under the Slope PWM item.
