I think all sections can handle a 120 or 140mm. I will have an optical drive in front which I think will block a section (it can fit 3 fans total) in the front from putting a fan so it will allow only 2 intake.

If I was to upgrade after I felt it was running too hot, would I just want to add 1 exhaust fan to the top? I think that would make a neutral airflow, correct (2 intake and 2 exhaust)?

I am new to building and am looking for suggestions on airflow/fan configurations. The mastercase pro 5 comes with 2 fans in front and 1 in back as stock (both 140mm). Will that be enough? Do I need to add 2 fans on top for additional exhaust? Any suggestions are welcome.
