Doesn't really apply to this conversation a whole lot, but this statement reminded me of a discussion I got into a few years back about wind chills. It does not affect vehicles, only warm blooded creatures. There has to be a heat source, like your skin, that the wind can wick heat off of. It might cool the rad off faster, but once it reaches ambient air temp, the wind no longer affects it.
Just thought I would throw it into the mix.
