I would have thought the same, but once i was going up hill and
towing a light trailer on a hot day (~100F, maybe ?), oh, and
running the AC. The temperature creeped up until the thermostatic
fan kicked in (roar!), and then the engine cooled off.
So, there was some airflow to be gained.
The truck was only a year or so old, so there weren't any cooling
system issues that i know of.
