IMO, I would go with at least 8 inch on either side. Larger on the out-take if possible.
Too strong? Get a speed controller...

Trust me and do yourself a favor... Do a "dry" run with no live plants in the room and see how hot/cold it goes. Take care of your ventilation and/or HVAC before you actually grow anything.

As far as carbon filer size... that depends on the size of the room and how stinky your plants are. I believe that bigger is better when it comes to safety.

good luck!

Take a look at the ventilation 101 thread it will give you all the information you need. Concerning CFM's for ambient rise in temp, intake size needed per CFM and setting up a properly ventilated grow op.
