What’s this sound?

Anyone recognize what might be causing this?

More whiney or squeaky? Sounds like accessory belt.

Fan bracket bearing?

I think more of a squeal than a whine. Becomes louder with more rpms.

I replaced the serpentine belt, belt tensioner, and idler pulley and the issue seems to have been resolved.

Looking forward to not doing that again for a long time.
