Crisp sound PH315-53

Hello.
My first post here, so be kind

I've got a Predator PH315-53, about 5 months old.
Today, I was sitting by the laptop and could hear a crisp sound coming from the CPU fan/middle of the computer.
The noise became lower when I unplugged it from the charger, but still there. 1st second after unplugging, the sound dissapeared completely, but after that came back but reduced sound.
When I plug the charger back in, the noise instantly volumes up again.
I dont think it's the fan though, since if I turn up the fan, the noise is still constant.

Anyone had similiar issue? 
The noise itself can barely be heard unless you get up close with your ear.

Thanks in advance.

Hi @ kimpis 

When the magnetic sheet steel inside a charger is extending itself, it is common for it to create a vibration. This vibration may make a high pitched noise due to the changes in the magnetics. When this happens, there is usually nothing to worry about.
