Are you growing in the full closet or a box with those demensions in a closet?
I have a small closet setup with 2 80 mm computer fans and a120mm for exhaust. Seems to be fine for me.

u dont really need much even openin the closet during day cycles is enough

use a small desk fan in that area for a small breeze

The area is my entire closet. Yea i have been leaving the door cracked during the day but i figured it would have to be sealed when i start flowering in there. So i could only open my closet on the on hours of light.

Everybody says "with a closet you do not need awesome ventilation. 99% TRUE. But of course I HAD to be the different one. I have 550 Watts of CFL< Flouros and MH (HPS for flowering) and the heat build up tends to be a bit much (of course it does get to be 120 before noon here many days. You have to judge for yourself. The PC fans work well, but I find that raising up the platform that the planters sit on about 3 feet allows me to save my back from bending over and put a fan blowing UP from under and I put a hole in the middle of the base. Then I put a passive exhaust out the top.

when you are doing intakes/exhausts remember 1, 90 degree angle is enough to block light, but 2 is a sure fire way to block more.

I have black visqueen over the windows in my room to prevent sunlight from coming in. That way, I can have my closet door open all day.

This is more for the co2 then for the heat. This closet is the closet that leads to the attic and i can crack the board the rests on to let as much heat rise into the attic as i want.

And i forgot to mention that, I wanted to vent this closet so the plants don't have a co2 deficiency, nothing to do with heat.

if you are using hid lights you will want cool air. usually one of the closet walls wil be an exterior wall. i used to run 6 inch ducting through the wall and i pulled air from under my house(nice cold air) and no light. or you can go right through the floor, you can hook up inline fans to pull the air. just a thought
