options in the BIOS, and is required to be implemented in all fan speed control
modes.
The Early Alarm is enabled when the Tctl value = 65, and is disabled when the Tctl
value drops from 65 to 62.
The Default Alarm (default setting) is enabled when the Tctl value = 70, and is
disabled when the Tctl value drops from 70 to 67.

•Onboard buzzer or speaker is required to be ON and to be a continuous sound.
•All system fans are required to be operated at full speed.
•System monitoring software (such as Super Doctor and IPMI if available) is
required to report and record CPU overheating events in the event logs.
When COA (either Early or Default Alarm) is disabled, the following actions are
required to be executed:
•System overheating LED is required to be OFF.
•Onboard buzzer or speaker is required to be OFF.
•All system fans are required to be returned to a normal, non-CPU-overheating
LFSC condition.
