your running an ac unit in a 5x5x5 foot room?
Intake is for circulating fresh air into your room, not nessisarily cooling.. You might be able to get away without one if your area isnt fully air tight, but you'd have to have a decent amount of airflow coming in, which means big gaps under doors, etc.
You'll need one unless your adding Co2
You will need an air intake and outtake to bring Co2 to your plants (unless ur suppling it)!!
A fan that moves like 400 cfm i believe will work fine

I think you would be fine....I have almost the same set up, mines 4x4x7 with a 5,000 btu window a/c.... I have a pair of 4'' computer fan's for the intake at the bottom.... Im in florida where its 90+ outside everyday and my temps stay between 70-76.... It also will depend on what size light you have... im only running a 400w hps.
