What makes you feel you need increased air circulation in such a small wine cooler? I have two 28 bottles Vinotemps and have not used any fans in the past two years. I did use Oust fans when I first set them up, but the way they ate batteries I just took them out. I have not noticed any difference in the way my cigars smoke. Remember its not the Rh of the air that matters, only the Rh inside the boxes or trays.
