CPU FAN Fail Warning/1st/2nd/3rd/4th SYSTEM FAN Fail Warning &
Allows the system to emit warning sound if the CPU fan or system fans are not connected or fails. Check
the fan condition or fan connection when this occurs. (Default: Disabled)
CPU Fan Speed 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. 
