Why has my CPU started emiting scratching/ whining noises?

Why has my CPU started emiting scratching/ whining noises? My laptop has recently started to make a peculiar high pitched whining/ scratching noise, after taking a good long listen, and testing both my fan and my hard disk, I'm 100% sure this is my CPU that is making the noise.
