The present invention provides a control system configured to reference a data structure, such as a look up table, to variably control fan speed based on ground speed of an agricultural machine, independent of engine speed of the machine, to achieve a given application rate for a field. In one aspect, the control system can control a Pulse Width Modulation (PWM) solenoid to a pump causing a transfer of a given amount of fluid to achieve a correct fan speed according to the data structure. As a result, fan speeds can be prescribed for any application rate, such as a light application rate of 100 pounds per acre, with slowing the fan down, or a heavy application rate of 1000 pounds per acre, with speeding the fan up, all as a function of ground speed, while decoupled from engine speed.
