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 ef...

My experience with many different computer fans says if there is to be resistance to airflow, better that resistance be in front of the fan, rather than behind it.
The blades trying to scavenge air through resistance makes them much less effective, and louder.
High static pressure rating is achieved most effectively, by increased rpm.
Since you enjoy Dual ball bearing fans, Delta makes some top quality fans some of which can turn at obscene rpms.
I have a delta PFB0912uhe, a 92 MM fan, on a voltage bucker which shaves a volt off the top. Still so powerful that loss is of no concern, and i can reduce fan speed to silent via a 10K ohm remote pot.
They have very powerful 80Mm fans too.

That Somnabeech is a air moving machine.
The blades in front of the impeller concentrate the airflow.
My 92MM fan column of air spreads only to 10 inches diameter at 3 feet.
