A system includes a genset having an engine, an AC generator, and a radiator thermally coupled to the engine. The system includes an electric variable speed fan having an outlet flow, where the outlet flow passes at least partially through the radiator. The system includes a controller structured to functionally execute certain operations for cooling the genset. The controller interprets a genset identification parameter and selects a cooling algorithm from a predetermined set of cooling algorithms according to the genset identification parameter. The controller further interprets genset operating conditions according to the cooling algorithm, and provides a cooling fan command in response to the genset operating conditions and the cooling algorithm. The electric variable speed fan is responsive to the cooling fan command.
