You could buy one of those plugs that have transformer integrated in them with selectable voltage. They always have those from 2V to 12V. You will need to do a bit of wiring, but nothing complicated, just connect the +/- cables of the fan to the jack of the transformer/plug. I'm sure they have these at any electric/hardware store.
