No idea, there's not enough information in your question for me to give a thoughtful answer. Open the hood, try to hear where the noise is coming from. Use adequate care, don't get your tie, hair, jewelry, clothing or anything else near moving parts. If you can't tell what it is, find a GM specialist.
