Abstract
A control system for use with a machine having an engine is disclosed. The control system may have a cooling circuit, a heat exchanger associated with the cooling circuit, and a sensor configured to generate a signal indicative of a temperature of the cooling circuit. The cooling system may also have a fan mechanically driven by the engine to direct air through the cooling circuit, and a controller in communication with the sensor and the engine. The controller may be configured to adjust a speed of the engine based on the signal.
