Sounds like Fan clutch, water pump or alternator.
You can take the belt off for the alternator. start it and see if the noise goes away. if it does it's the alt.
If it doesn't put it back on and remove the fan, but not the fan pulley. Put the nuts back on to hold the pulley on start it up and see if the noise goes away. If it does, replace the fan assembly.
If it doesn't it is more than likely the water pump.
