So, for the last three weeks or so since I've had my car, I've noticed that when I start it up, the first 90 seconds or so, there's a loud whirring sound. I called the service center and they said it's normal and most ICE cars do it, we just don't hear it because it's part of normal engine noise. So, my solution has been to leave the climate off, until I start driving, then immediately turn it on. For some reason it doesn't make any noise after I'm driving even speeds as low as 1-2 mph while I'm still pulling out of my parking space. I didn't know if you guys were having this issue too, but if so, hopefully this address your issue. YMMV.
