Dealing with the ceiling fan (I don't have one so I can't relate) I would be more concerned with soot and actually burning of the candle. If my wick is the slightest bit too long and I get a draft, I get soot. Being the scientist that I am, I wonder if you have the fan with the blades turning so the air pushes down (you might have scent pushing down toward the ground) I wonder if you got down lower than the candle if you would smell it there? Or, if you have the blades turning the other way, that it is sucking it out of the room and the scent is up by the ceiling? I would just turn off the fan.
