BIOS Setup

  Current System/CPU Temperature

Displays current System/CPU temperature.

  Current CPU/SYSTEM/POWER FAN Speed (RPM)

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 CPU/system/power fan is not connected or fails. Check 
the fan condition or fan connection when this occurs. (Default: Disabled)

  CPU Smart FAN Control

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 configurable only when CPU Smart FAN Con-
trol is set to Normal. Options are: 0.75 PWM value /

o

C ~ 2.50 PWM value /

o

C.

  CPU Smart FAN Mode

Specifies how to control CPU fan speed. This item is configurable only when CPU Smart FAN Control 
is set to Enabled. 

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.

Note: The Voltage mode can be set for a 3-pin CPU fan or a 4-pin CPU fan. However, for a 4-pin CPU 
fan that is not designed following Intel PWM fan specifications, selecting PWM mode may not effectively 
reduce the fan speed.
