where are your intake holes?
passive(hole) or active(fan)

What CFM rating is your fan?
Is the fan sucking the air out or blowing the air in?

What is the temperature at the floor of the space?
your thermometer may be measuring radiant heat.

Is there a fan inside the closet?


You gotta get the air moving...
