I don't know which part it is specifically on the e46, but it sounds like the bearing on an idler, tensioner, or possibly a driven accessory.
The problem with driving it is if something does seize and the belt breaks at high rpm, it can grenade other stuff like the cooling reservoir, fan, radiator, or even put dimples in the hood.

I would remove the mechanical fan first and see if the noise is still there. If it is, then look at the pulleys and belts.
Either way look into doing the electrical fan mod

You know that sneezing man button on your steering wheel?
Press that button for 2-3 seconds, while keeping it pressed in, turn the ignition to the second position, keep it pressed for 2 or 3 more seconds and then release. It should say BT PAIRING on your radio display at that point. Pull out your phone and make sure bluetooth is on then search for devices like you would connect to anything else. Enter the PK and you're good to go.

"I've always thought of the hardcore ZHP owners as a bunch of pricks that over value an option package, this cements that position."
Nothing came up when I tried that...
