BIOS Setup
& Case Open
Displays the detection status of the chassis intrusion detection device attached to the motherboard CI
header.Ifthesystemchassiscoverisremoved,thiseldwillshow"Yes",otherwiseitwillshow"No".To
clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings to
the CMOS, and then restart your system.
& CPU Vcore/Dram Channel A/B/C/D Voltage/+5V/+12V/CPU VTT
Displays the current system voltages.
& CPU/PCH/System Temperature
Displays current CPU/Chipset/System temperature.
& CPU/System FAN Speed
Displays current CPU/system fan speeds.
& 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 Fan Fail Warning
Allows the system to emit warning sound if the CPU fan or system fan are not connected or fail. 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.
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specications,selectingPWMmodemaynoteffectively
reduce the fan speed.
& 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.
& 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 /

& System Fan Speed Control
Allows you to determine whether to enable the system fan speed control function 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)
