This sounds a lot like an engineering argument....The engineer will tell you
something doesnot or could not possibly work, where as the shade tree
mechanic will show you that it does................

I live in a humid hot area, and when i go in my van to an area that is not
as humid and the temps and altitude are basically the same, my oil temps are
lower..........

Theory may say otherwise, but anyone that has actually seen their gauges
react differently under similar load and same oil the only difference being
humidity............  Rain cools the case.humidity does not.
