Abstract
A device comprising a temperature measurement module, a performance state module, a memory bandwidth module, and a fan speed module. The temperature measurement module is configured to determine a rate of temperature change in a server and to output a control signal when the rate of temperature change is above a threshold rate. The performance state module is configured to reduce a performance state of the device to a lowest system level in response to the control signal, and 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 level. The memory bandwidth module is configured to reduce a memory bandwidth to a minimum bandwidth level based on the control signal. The fan speed module is configured to reduce a fan speed to a minimum level based on the control signal.
