Abstract
A device includes a fan and a processor coupled to the fan. The processor includes a system management unit configured to detect abnormal operation of the fan in response to a speed of the fan satisfying one or more conditions. When the system management unit detects abnormal operation of the fan, the system management unit reduces one or more protection temperatures including a throttling temperature and a shut-off temperature.
