A fan itself won’t really help with the humidity levels in your cellar, but it will help with getting air moving into the room from other areas such as the rest of the house and outdoors.

What humidity grows mold?
Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth. Indoor relative humidity (RH) should be kept below 60 percent — ideally between 30 percent and 50 percent, if possible. Low humidity may also discourage pests (such as cockroaches) and dust mites.
Can mold dry out and die?
Mold spores never truly “die” because they can always begin to multiply again at a later time if new moisture becomes available. For this reason, you should always go one step beyond removing the moisture. After drying the mold, you should also remove the spores themselves from your home, using a vacuum cleaner.
