I can't think of any case I've ever seen where it would be a good thing to
have all fans trying to exhaust air out of the case. All this would do is
create a vacuum in the case, with little or no airflow. You generally want
intake and exhaust air to be equal in volume. For example, with the power
supply fan exhausting hot air out of the case, installing a secondary fan
at the lower front (for most cases anyhow) to pull air into the case would
be very helpful.
http://www.overclockers.com/ is a great resource for all things related to
cooling. Regardless of your opinion on overclocking, the site has a huge
amount of information on effective cooling methods that range from mundane
(adding a secondary case fan) to the truly wacky (evaporative cooling
tower).
