A few questions...

1. Does the intake fan have to be the same size as the outtake fan?
2. If the fan is a decent make (Arctic Cooling) can it be left on 24/7, or should I get 4 fans - two intake and two outtake, and have them on alternately?
3. My closet is 2.5ft wide, 5ft high (250w HPS hanging down 2 foot above the ground though with reflector) and 2.5ft deep. What size/diameter fan should I get, and what RPM should it run at? The temp is fine at night because I have a fan blowing cool air on me while I sleep, but during the day its running between 27 and 31C
4. A 12v computer fan can be wired up to the mains, am I correct? If so, I can look up on Google on how to do this
5. Intake fans run level with the plants, whilst outtake fans run just above the light - yes or no?

Cheers for your time peeps
