How many miles are on the car? To me it sounds like a pulley bearing from one of the accessories is going bad. That was an awfully quiet video though.
It's currently at 26k miles,
When I get home to my computer, I'll edit the video to try and crank the volume up on the noise,
It does sound like a wobbly bearing.
I'm gunna get someone to help me set the RPMs to trigger the noise- and deep dive in the hood to find where exactly it's coming from.
Sorry for the super quiet video, it's all I had on me to record the noise
