<> 2. The only way to make uniform air flow is with restriction.

<In other words: ducts and shrounds?

Thats it and ample power to motovate the air.

<Tell me about this "rotating air will do strange thing till
<straightened out" what it do strange thing? And how is done to
<straighten it out?

Air does not go through a fan smoothly and the rotation of the fan
plus aerodynamic effects imparts a spin on the air. That air will
not travel nicely.

<Do tell your tales about this! I'm trying to design a case to do
<cooling of all drives, PSU motherboard and CPU by one large quiet
<fan and ducts/shrounds. Isssues: noise and reliablity from too many
<fans.

Harder tha it looks as each drive has a differnt fit and different
air flow. Plan to use a big blower rather than a fan. Also air at
higher pressure can transport more heat so a 200cfm imparting a static
pressure of and inch of water along with airflow will cool better.
IT will also be noisy!
