The fan can turn some unsafe strings into safe strings. Input the fan throw at the end of a blocked string, and as long as your opponent is blocking you will be safe; however, if instead of blocking your opponent crouches (without block)at the end of the actual string the fan will go right over their head leaving you open to a punish. So if you are playing high level players and you abuse the fan to make block strings safe they could read you and crouch then punish so make sure you vary this tactic.
