PROFILE BASED FAN CONTROL FOR COMPUTING DEVICES

摘要

An unmanageable component may be any component in a computing system that does not expose a temperature sensor thereby preventing the component's temperature from being monitored. The embodiments described herein control a fan using settings that decrease the likelihood that an unmanageable component will overheat. Before a user-selected fan profile is used to control the fan, a power system management uses safeguarding profiles to mitigate the risk of overheating the unmanageable components in the computing system when selecting a fan profile. Stated differently, the power management system ensures the computing system does not use the user-selected profile to operate a fan if that profile may cause an unmanageable component to overheat.

1. A method comprising:
identifying an unmanageable component in a computing system, wherein a temperature of the unmanageable component is unknown to the computing system; identifying a component specific profile corresponding to the unmanageable component, the component specific profile defining a first fan setting for cooling the unmanageable component; determining whether a second fan setting of a user-selected profile can adequately cool the unmanageable component based on the first and second fan settings; and upon determining the user-selected profile cannot adequately cool the unmanageable component, controlling a fan in the computing system based on the component specific profile instead of the user-selected profile.
