[. . . ] Enabled clears the record of previous chassis intrusion status and the Case Opened field will show "No" at next boot. (Default: Disabled) 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. - 51 BIOS Setup Reset Case Open Status Case Opened Current Voltage(V) Vcore/DDR3 1. 5V/+3. 3V/+12V Current System/CPU Temperature Current CPU/SYSTEM/POWER FAN Speed (RPM) CPU Warning Temperature Displays current CPU/system/power fan speed. Displays the current system voltages. CPU/SYSTEM/POWER FAN Fail Warning 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. Allows the system to emit warning sound if the CPU/system/power fan is not connected or fails. (Default: Disabled) Enables or disables the CPU fan speed control function. Enabled allows the CPU fan to run at different speed according to the CPU temperature. You can adjust the fan speed with EasyTune based on system requirements. This item is configurable only if 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. Enabled allows the system fan to run at different speed according to the system temperature.
