Someone figured out (I forget who or where I read this) that the dreak-even point (at least for their vehicle) was around 40 MPH. Above this, the engine cooler reduced the heat more than the engine produced (up to a point, naturally), while below this, the opposite was true, which seems to be what you've experienced.
The question being answered on that other thread was "If I'm worried about my engine starting to overheat, when does it make sense to pull over vs. drive so the airflow cools the engine?" or something along those lines. Seems like the implications of his statement were if he could drive in the 40-50 MPH range, then he would, otherwise he'd pull off and let the engine cool. At least, that's what I took away from the discussion.
Perhaps someone else recalls what I'm trying to say and can correct me if I've gotten it wrong.
