The location access is often needed for the app to be able to find the WiFi networks in the neighborhood. This is because that can be used to triangulate your location, so they bundle it in with the same permission (unfortunately, there isn't a very good way to separate this, since it theoretically can be used to locate you and therefore you should let the user know that).

Why does a fan app need to find the WiFi networks? The OS does this, and then serves an internet connection to the app. It doesn't need to know what the available networks are.
