ファンクラブ is the default for entertainment fan clubs. 後援会 is used for more formal support groups, like those for sumo stables, politicians, or local performers. Using 後援会 for a pop idol fan club would sound overly stiff.

He formed a local supporters' association.
If you want to say 'my fan club' meaning a group of friends who are fans, ファン仲間 is more natural than ファンクラブ, which implies an official organization.
