Yes, digital servos are a lot noisier than analogue servos. Both my 7955s are the same - a sort of clicky/crunchy/squealy noise, rather than a mechanical whirring.
They also make a noise when they aren't moving, if the wheels are on the ground. Nothing to worry about.

The noise is comon with any digital servos, because they try much harder to maintain center. It has nothing to do with the coreless motor. Lift the wheels off the ground to unload the servo. Quiet now? Yup, that's how they work.

Cheers.
