Push Or Pull Muffin Fans (?)

Lesson time for Mex.

Is there a difference? Some more suitable for case exhausting than others? Push air in? Pull air out? I take advantage of natural convection effect but if some fans are more efficient than others I wish to learn about them...

Thank you....

    The only thing you have to watch is the the fan is located in a bulkhead or tube (duct). Otherwise the fan creates a low pressure on the suction side and the higher pressure air on the discharge side circles back and much of the air is just recirculated at the fan.

    a 12-v muffin fan can do both. just turn it around or reverse the wiring. i prefer to exhaust air.
