US Patent 7167015 Active cooling to reduce leakage power

Leakage power consumed by an integrated circuit is estimated as the difference between total power consumption and a nominal expected power consumption. Leakage power is reduced by cooling the integrated circuit in an active cooling system. By expending power in the active cooling system, the integrated circuit is cooled and the total power consumption is decreased. When the decrease in total power consumption is greater than the power expended in the cooling system, an overall power savings is achieved.
