Hard to say for sure. I would start by removing the serpentine belt, then run the engine for a short period of time to see if the noise is still there. If it's gone, you know it's one of the accessories that runs off the belt drive. Attached is a picture of the belt routing and the remove and install procedure for the belt. Let me know what you find!
