&& CPU Vcore/Dram Voltage/+3.3V/+12V 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), 60oC/140oF, 70oC/158oF, 80oC/176oF, 90oC/194oF. && 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 specifications, 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 configurable only when CPU Fan Speed Control is set to Manual. Options are: 0.75 PWM value /oC ~ 2.50 PWM value /oC. && 1st/2nd/3rd 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 fans 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. Disabled Allows the system fan to run at full speeds. && Slope PWM Allows you to control the system fan speed. This item is configurable only when 1st/2nd/3rd System Fan Speed Control is set to Manual. Options are: 0.75 PWM value /oC ~ 2.50 PWM value /oC. - 51 - BIOS Setup
