Abstract
Embodiments of the present invention are directed to systems and methods for controlling the temperature of an internal device while reducing or minimizing the involvement of the host. Thus, some of the heat monitoring and remediation work may be offloaded to the actual device itself. The device may monitor its own temperature and, in the event of high temperature, perform device specific heat reduction actions without involving the host. Furthermore, the device may, upon detecting temperature within a predefined range, alert the host of a high temperature condition in order to allow the host to perform temperature reduction measures. Also, the device may, upon detecting temperature within a predefined range, alert the host of an impending device shutdown and shut the device down. In addition, the device may periodically save its temperature into non-volatile memory in order to create a temperature log.
