Remove the fan from the viscous drive, then the A/C drive belt. Run engine and see if the noise is gone. If not remove the main drive belt and run again.

While each belt is off, check the tensioner pully bearing for roughness and play - my air con tensioner was running dry. Also check the needle roller arm pivot bearing - I fitted an 'O' ring on each side to provide a decent seal.
