Yes. The connections are all correct. I'm using the MakerFarm fan extender, which is manufactured by RepRapDiscount. It has a dual buffer driver and a jumper to provide 12v power. It has two fan channels, on D4 and D5, but it covers all four servo pins. I soldered a header with three pins to the D11 pins on the top of the fan extender, and that's where I plug in the servo. The only connections on the board are D4/D5, so the other two are available--just covered. It would be awesome of they used a wire wrap socket so the pins extended out the top for this purpose.
