Humidifier yes : Humidification as well as oral fluids can loosen nasal secretions which may help certain cough. A fan will not help.

Probably not: Generally cough is caused by one of a few things. The most common causes of cough include mucous in the throat or chest, infection in the chest, obstruction in the airways (such as with asthma), or other irritation of the airway (such as with acid reflux or irritant inhalation). Because a fan or humidifier don't address these issues, they are unlikely to be of benefit and i don't recommend them.
