Laptop CPU/coil whining?

So my mother has got a Satellite from Toshiba which does weird sounds while file browsing or watching videos - I did a little bit of research and found out that working processors including CPUs and GPUs tend to produce such issues. Now I am not sure what exactly causes these sounds but I put up a brief video so you can listen to it and comment what you think about it and perhaps how to fix it:

That is a very strong sound. Hope somebody has an answer for you.
