i would get a 12 volt adapter and just wire them in parallel. way better bet. they cost like $1 at most thrift stores

Why not spend like $10 and wire each up separately with the proper adapters instead of trying to ghetto rig something that will probably reduce the operating lifespan of your fans and be a potential fire hazard?

yeah for sure it will. just wire all the negative wires together and all the positive ones and hook it up
