Passive Intake and Fan questions

  1. I have a 120cf ward closet. I will be using a 450cfc Inline HO fan. Basically it will go like this
    Carbon filter----400w sealed hood-----fan------exhs exit. How many and how big of holes should i put on the bottom of this closet to make it take in the right amount of air. I h ave herd 5 times the size of the intake (that would be to big) i have herd a couple little holes will work? What do you guys think? I am trying to make sure there is great airflow as it gets up to 115 degrees here in the summer. And i want this cab to have fresh air all the time. What cha think?
  2. I might also use Hood---carbon filter--fan--exh which one is better?
  3. Anyone have any idea??
