Bad Zfr bearings?

Hey guys. I’ve got a fbo e47 tuned lnf with a 6758. Runs like a top. Recently, when I shut the car off I can hear like a “whirring” noise coming thru my intake, (k&n) and I’m worried it might be my turbo bearings going bad. It also makes this noise at idle. Something i should be concerned about?
