I'm sure I seen the wiring on yours in a post but could not find it for toffee, but it's out the port side if I remember right, maybe it's the vibes from that combined with the wrap, as the airflow goes over it,
This is just a guess mind Derek, something has to be transmitting vibes as I can leave mine alone for a good few seconds and it does nowt, and that's on V3.1 which is tip over Central,
Make sure you give your bearings a light oil as well this will help it greatly with smoothness, I use heli options bearing oil with nano particles, lol
