Laptop / Notebook from DELL crackles as soon as it works?

A question to the computer or laptop experts. My relatively new DELL laptop (about 8 months) crackles or rustles as soon as it has a bit more to do. Sometimes it is enough to open only the browser, and while the part is crackling.

And pretty much in the middle behind or under the keyboard. Now I would have to open the device to know what exactly sits at this point under the keyboard.

What could basically crackle like that? Processor? R.A.M? Hard disk?

I know this crackle only from relatively old hard drives, just before they have quit their service.

EDIT: It's an Inspiron 5770 with Intel CORE i5

Crackling, I would rather associate with the transformer / power supply, but does not fit in with your description of the origin.

A rattle / clacking is assigned to the hard disk.

In general, it is not okay if it makes such sounds. Take your guarantee and let it fix it.

With a very quiet notebook, it may well be that you hear the work of the record or the start of the fan when it gets warmer.

Record and post sound

A crackle comes normally from the electricity. However, this is very unlikely in your case.

The first thing I would do is tap the hard disk, it makes the most noise. The fan may be too, but then the noise would have to disappear at a high speed.

I have now recorded noise. How can I post it here?
