Very common (both the EEs and the inblowing air :-))  Nor am I claiming
to be a great airflow expert.

What I was saying, though, doesn't really depend on whether it was
designed by somebody who had a clue about airflow or not; it was likely
checked by someone who determined that it worked "well enough" under
some set of conditions.  Changing something like the direction of
airflow *without consideration of the consequences* is a bad thing.
 I'm not suggesting the airflow couldn't be improved one way or
