The invention relates to a radiator fan system for cooling and/or heating a drive device, in particular a fuel cell system (16), for arrangement in a vehicle. The radiator fan system has at least one blower (1) having at least one driven rotor (3) rotatable about an axis of rotation (D) for moving an airflow in a main flow direction (9), having at least one rotor blade (4) arranged normal to the axis of rotation (D) with respect to a rotor plane (RE). The blower (1) has at least one radiator shutter (5) upstream and/or downstream of the rotor (3) in the main flow direction (9) for closing the radiator fan system, the radiator shutter having shutter blades (6) arranged radially around a central axis (M) and pivotable about a pivot axis (S) normal to the central axis (M). The radiator fan system is characterised in that the shutter blades (6) in an open position are arranged normal to the central axis (M) with respect to a shutter plane (SE), and in that they are arranged in opposition to the rotor blades (5).
