car overheating and loud fan and i don't know why

What is your question?

i own a corvette c5 2004 and when i start my car my exhaust fan on the driver side makes to much noise. it used to be much quieter but now it extremely loud and is clearly louder and annoying while driving the car. I think it could be a problem in my cooling system because the same week my car overheated while i was driving and the coolant gauge was over 240. could it be a problem in my water pump or cooling system?

What makes this problem better or worse?

its worse when i drive

How long has your 2004 Chevrolet Corvette had this problem?
