&& 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 field 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 Voltage/+3.3V/+12V Displays the current system voltages. && CPU/System Temperature Displays current CPU/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 fan is not connected or fails. Check the fan condition or fan connection when this occurs. (Default: Disabled) && CPU Fan Speed Control (CPU_FAN Connector) Allows you to determine whether to enable the fan speed control function and adjust the fan speed. Normal Allows the 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 fan to run at slow speeds. Manual Allows you to control the fan speed under the Slope PWM item. Disabled Allows the fan to run at full speeds. && Slope PWM Allows you to control the 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 System Fan Speed Control (SYS_FAN1 Connector) Allows you to determine whether to enable the fan speed control function and adjust the fan speed. Normal Allows the 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 fan to run at slow speeds. Manual Allows you to control the fan speed under the Slope PWM item. Disabled Allows the fan to run at full speeds. && Slope PWM Allows you to control the fan speed. This item is configurable only when 1st System Fan Speed Control is set to Manual. Options are: 0.75 PWM value /oC ~ 2.50 PWM value /oC. && 2nd System Fan Speed Control (SYS_FAN2 Connector) Allows you to determine whether to enable the fan speed control function and adjust the fan speed. Normal Allows the 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 fan to run at slow speeds. Manual Allows you to control the fan speed under the Slope PWM item. Disabled Allows the fan to run at full speeds. && Slope PWM Allows you to control the fan speed. This item is configurable only when 2nd System Fan Speed Control is set to Manual.
