Sounds like bearing rattle (for example in the alternator) but the video is too short to really tell plus the cooling fans were running half the time.

Thats a idler or tension pulley bearing hopefully not a water pump or alternator (where the serpentine belt goes) let us know what it is.

Sounds like the water pump bearing is eating itself. If you'd like to find out definitively if it is the water pump, remove the accessory belt, and turn the WP pulley by hand. It should be smooth and have no in-and-out play AND no side-to-side play. With the right tools, it'll take 5 minutes to remove the belt and re-attach.
