I think you are cathected into your neck. This means you are obsessed with your neck noises for some reason that you or I cannot fathom.
If you have no pain, and these noises occur, even if they are loud, you need to ignore them. You need to gain control of your attention and “push” your mind away from the sounds. This will take some hard work but you can be successful.
Stretching can increase the sounds your neck makes. Consider dropping PT and resting your neck somewhat. A stiffer neck will be less “noisy”
