What is the best way to set your case fans (3-4 fans) all in or
blowing out or somewhere in between


Generally one more fan blowing in than out, taking into consideration
the
PSU fan.

This creates a positive pressure in the case.

This depends totally on your environment. In a dusty environment, yours
is a good solution - no air and dust entering case through drive openings.

In a low dust or no dust environment, you *want* cool air flowing over
your drive devices, so exhaust fans should out number input fans, that
is, more fans blowing out than blowing in.


Why does more exhaust fans mean more air ?
