Is a slight eclectic surren in the laptop normal?

Have bought a new laptop and when I hold my ear to the fan shaft I hear a slight electrical whir. Is it normal?

Sure, of course. The absolutely inaudible fan does not exist. Moving parts make noises.

But when surfing he is out and you still hear it

High-frequency beeping is normal for certain components, you can't do anything.

I beg your pardon? When surfing who or what is out? The laptop hardly, so the fan is not. And apart from that, that's not the only moving part. If a HDD is installed, also makes the noise.

That will be added, yes. Keyword "coil whip".
