It'd be better not to have the fan blowing directly on the buds because it could direct dust or anything else in the air towards the buds, which wouldn't be good at all. Once they are dry enough to the point that the stems can snap with ease, don't put them in paper or plastic bags. Place them in glass jars that are airtight and place these somewhere dark--light and air degrade THC. Just open the jars every day at the beginning and check out the buds for any excess moisture or any signs of mold.
