Can circulating fan(s) inside the refrigerator help-- SURE.
But, limiting the intrusion of hot, humid air into the refrigerator (from whatever source) is also important. Not sure a debate over which is more important is relevant.
What the fan(s) can do by circulating air over the fins is keep the fin temperature above 32 degrees F. So, moisture can condense (and take cooling BTU's to do so), but it then drips into the tray and out the condensate tube. Is this a good idea-- sure.
Combine this with minimizing the amount of moisture intrusion into the refrigerator and you have the BEST answer.
