Abstract
A cooling apparatus for an integrated circuit. The cooling apparatus comprises cooling fan means, a control circuit and heat pipe means. The control circuit determines a spinning speed of the cooling fan and an operation performance mode of the integrated circuit according to the load and the temperature of the integrated circuit, the ambient temperature and a reference temperature. Within a tolerable range of the output of adder means, the heating pipe means continues dispelling heat of the integrated circuit without turning on the cooling fan. While the output of the adder means exceed the tolerable range, the fan is turned on to enforce the heat dissipation.
