    It could be that the cooling fan clutch is stuck on causing increased fan noise at freeway speeds. The fan clutch is designed to disengage the cooling fan at freeway speeds when air flow created by the vehicle speed is sufficient to cool the radiator. If the fan is "stuck" on it can create quite a roaring noise while driving.
