The 3 inch muffin fan does not move enough air for this application. Also this type of fan is not intended to run with this type of mounting. It is meant to cool a tightly enclosed space and is not IMHO sufficiently directional. Also it would be vulnerable to jamming if foreign objects fell on it or were sucked up into it. The open bladed fan that came from Dometic is preferred for this reason as almost anything that came near it would be pushed away, string and hair excepted. I have had good results with replacements that are marketed as auxiliary refrigerator fans at RV supply stores. I buy them at Camping World and they come with mounting bracket for $25.
