Super question.  This is why racers (especially street cars converted 
to racers)
cook their front wheel bearings on a more regular basis.  So I'd have 
to go with
that a certain amount of heat dissipation is 'built-in', but gets 
better with airflow.
People have already noticed how much hotter the system seems to run with
closed in rims like the teardrops for instance.   I've read stories 
of race cars having
to retire, or run quite a bit slower, because some front end damage knocked out
their brake ducts / or cooling...the rest of the system wasn't up to task of
dissipating the heat generated by the brake system on a car running fast laps.

This is a great discussion BTW, and I don't consider it a flame-war 
for the record. :)
