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/POWER FAN Fail Warning Allows the system to emit warning sound if the CPU/system/power fan is not connected or fails. Check the fan condition or fan connection when this occurs. (Default: Disabled) GA-EP43-UD3L/US3L Motherboard - 56 - o" CPU Smart FAN Control Enables or disables the CPU fan speed control function. Auto lets the BIOS decide whether to enable this 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. If disabled, CPU fan runs at full speed. (Default: Auto) v CPU Smart FAN Mode Specifies how to control CPU fan speed. This item is configurable only if CPU Smart FAN Control is set to Enabled or Auto. to Auto Lets BIOS autodetect the type of CPU fan installed and sets the optimal CPU fan control mode. (Default) to Voltage Sets Voltage mode for a 3-pin CPU fan. to 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. - 57 - BIOS Setup 2-10 Load Fail-Safe Defaults Press on this item and then press the key to load the safest BIOS default settings.
