Abstract
A device comprising a temperature measurement module, a performance state module, and a fan speed module. The temperature measurement module is configured to determine a temperature in a server, and to output a first control signal when temperature in the server is above a threshold. The performance state module is configured to change a performance state of the device to a lowest system performance state in response to the first control signal, and further configured to reduce a processor power consumption and a subsystem power consumption to a minimum power level in response to reducing the performance state to the lowest system performance state. The fan speed module is configured to reduce a fan speed to a minimum fan speed level based on the first control signal.
