ABSTRACT:
A personal computer has at least one heat producing element within its housing with a fan for cooling the inside of the housing. The fan is controlled by a temperature dependent fan control circuit. A heat sensing device within the fan control circuit adjusts the voltage applied to the fan in a substantially continuous relationship to the temperature inside the housing.
