Question Humming/Grinding noise at 65+ MPH

Attached is a video of the car operating when I hear the noise. If I lean closer to the windshield the noise gets prominently louder.

Any ideas?

Oh yeah that's not good ... does the pitch change with RPMs?

Is your AC functional? I had that same noise, my AC didn’t work and it went away after they replaced the compressor. However, I cannot say for sure that was the cause of the noise

No the pitch doesn't change. If I rock the steering wheel back and forth quickly it changes slightly. Sometimes it just goes away. No idea what causes it.

AC works like a charm...

Wheel ball bearing maybe? (Though one would expect that to change with speed somewhat)

There is a fan/motor somewhere in the front that turns on as soon as the car turns on. It gets louder during charger. Maybe its part of the cooling circuit. Do you notice when it starts and at what ambient temperature? Do you hear it when charging?

I think you're right. When I had my accident I got this noise and they had to change the wheel ball bearings.

Unfortunately it looks like something bigger. The car went in for service Thursday morning bright and early, as of today there's some fault code with the front motor. The service manager told me that Jaguar in New Jersey (I'm in California) advised that they should check the internal oil in the motor. That revealed the presence of metal shavings. Not sure what it amounts to.
Will keep anyone interested posted.
