You are right that wind chill shouldn't affect machinery, but wind chill has to do with evaporation of water from the skin, causing the skin (or a pan of water) to be colder than the dry bulb temperature. Since a good radiator is dry on the outside, wind chill as defined by the weather service has no effect. Sure wind will cool it faster, but that's not what the NWS wind chill number is. Dry air cools the skin more than damp air blowing by.
