Hi.
The decco vent is from home depot. Just search there for it.
Gonna need some more specifics.
How big and what kind of fans, and how are they placed? Do you have any air intake other than the door? Is there another room that shares the wall inside the closet? If so, how are the temps in there? Is your place Air Conditioned?
How are your temps normally?
Pics would help. If you have to draw one on MSPaint and it looks shitty, it will still help.
I'd be happy to help ya.
One word of advice (and not trying to be too harsh) get that myspace link off of your profile and ditch the self pic in there as well.
