What do you mean with "heat shrink" is making noise? Heatsinks don't make any noise, unless you mean the fan on top of it, or if you didn't mount it properly, in which case it probably would be rattling against other parts of the PC...

Fans on the other hand, as they need to turn to be of use, naturally make sounds. Of course if there are cables or other pieces obstructing the fan, those might make more noises.

Besides that, if you are overclocking, or always running the PC at maximum performance, will heat it up more, causing the fans to run faster, which of course will also make the PC louder.

So it might be the normal way of your PC.

It sounds like the fan is hitting then Heatsink but it is not. I have watch it and can not see it touching anything. It is a very loud sound like gears grinding. I have replaced both the fan and the heatsink 3 times but still making the loud sound
Thank you.

Maybe a recording of the sound might help, and maybe a couple of photos of the inside of the PC so we can get an idea.

post also the model of the pc
are you sure the noise comes from the cpu fan - and not from another one?  Power supply, or case fan
or even from a DVD player with a disk inside??
