Whining noise during operation

I hear a whirring/scraping sound. Check your waterpump (check for side to side play at the fan, visually check while running for any wobbling at pulley or fan). If all ok, check belts and items they drive for anything out of the ordinary.
 
When you have the hatch off and engine running, if its not obvious where the noise is coming from, use a long screwdriver and touch whatever part you want to try and identify the noise is from. Put your ear to the handle. Simple stethoscope.
