Sound advice from Weezard. Wouldn't touch the fans if possible, all you'll do is promote new growth which the plant has to find the energy for. If it's using energy to grow replacement fans, it's not hitting the bud sites with full beans. Just bend the fans out of the way or tie em to one side. The whole process is organic. When the plant doesn't need them anymore, they weaken at the node and are easily pulled off, or drop off.
