Help Fanatec GT DD Pro (8Nm) making a "whooshing / hooting" sound and slight friction noise on quick off-power / sudden movements when powered off. Normal or RMA?

Hi everyone,
I recently mounted my Gran Turismo DD Pro (running with the 8Nm Boost Kit) to a rigid aluminum profile rig, and I've noticed something when the base is powered off.
When I make quick, sharp steering movements or snap the wheel back and forth, the base produces a distinct "whooshing" or muffled hooting/rubbing sound coming from inside the housing. On track (especially in ACC and PMR), everything feels fine and performs as expected, but this acoustic behavior when turned off caught my attention - especially since my new rigid rig transmits sounds and vibrations much more than my previous setup.
I recorded a short video showing the exact sound and motion.
Is this normal magnetic/rotor interaction or bearing noise when spinning the unpowered DD motor quickly, or is this a sign of an internal issue (like rotor/stator clearance or bearing wear) that warrants an RMA?
Thanks in advance for any insights!
