Basically title, you always hear “windchill only affects humans” but we use fans to cool things all the time?

What “wind chill” actually means is that if you stood outside in naked skin, the effects on your skin/body are equivalent to being in a room with a temperature of WIND_CHILL.

It does this because air is not “nothing.” Wind Chill does “effect” objects, in that if those objects are in high winds for an extended period of time AND have chemical interactions with the air, then a higher wind would increase the wear on that object — just like the wind increases the “wear” on the human body.

This isn’t perfect, but should get you most of the way there.
