The fan will run until the temperature around the cooling fins has dropped below 106 F.  That may not be achieved quickly, since it does not evacuate the air to the outside.

I am considering a fan in place of the city water hookup, as I never use that.  I make it a point to avoid places that have city water available.  Not only are they almost always pricier than the better sorts of places, but the clientele is less to my liking (more RV types).  I think there is some information in the archives about fan choices.

Camped at Castaic Lake campground this past week where temps were over 100 degrees during the day. Now I understand the cooling fan is normally on during these times but it was also running almost the entire night as well. The fridge was running off propane and the outside temps during the night were in the 70's. Has anyone else experienced the fan being on almost constantly for 2 days? Does anyone have any pics of secondary cooling fans they have set-up or should I look into replacing my existing original fan??
