Summary:A method, computer program product, and a data processing system for maintaining operation of the data processing system in the event of a degraded system cooling condition is provided. A first temperature of a processor is identified as equaling or exceeding a processor throttling threshold. The operational frequency of the processor is reduced by a first frequency increment. The operational voltage of the processor is then reduced by a first voltage increment. Updated values of the processor temperature are periodically obtained and continued reductions in the frequency and operational voltage are made until the temperature indicates that the processor is operating in a stable throttle range. The frequency and operational voltage of the processor may be returned to normal levels when an updated temperature of the processor is less or equal to a throttle off threshold.
