12. A machine, comprising:
-
a hydraulic fan control circuit including; a variable displacement pump; a first hydraulic motor coupled to a first fan; a second hydraulic motor coupled to a second fan, the second hydraulic motor coupled in the circuit in parallel with the first hydraulic motor, each of the first and second hydraulic motors independently controllable via respectively controlled absorption volumes of the first and second hydraulic motors; and a control system including non-transient, computer-readable medium including instructions which, when executed by a processor, independently adjust fan speed of the first and second fans responsive to conditions, while maintaining the same supply pressure to respective inlets of the first and second hydraulic motors. - View Dependent Claims (13, 14)

15. A hydraulic fan control circuit for a machine, comprising:
a first hydraulic pump providing pressure to a first hydraulic motor driving a first fan, the pump further providing pressure to a second hydraulic motor driving a second fan, wherein a hydraulic motor driving torque of each of the first and second hydraulic motors is independently controllable by adjusting respective absorption volumes of the first and second hydraulic motor, while maintaining the same pressure provided to the first and second hydraulic motors.
