A faint sound coming from my new Asus Tuf A15

[Deadboy]

I got a new Tuf A15 a few days ago and yesterday I noticed a faint sound coming from it. I don't know how to describe it. Maybe like an insect chirping? I don't hear it on my older laptops.
It isn't loud. I can hear it in silence during the night or if I put my ear on the chassis during the day time.
I've uploaded the sound clip here.
I don't get this sound always.
Is this normal or could be a cause for concern?

Does it have a hard disk drive (HDD) and/or a solid state drive (SSD)? If it has the former, it could just be the sound of the read/write heads moving about.

Yeah, it has both HDD and SSD. So I guess I don't need to worry about it.

Given that they're very quiet clicks and random in nature, it's most likely to be the HDD. If those noises get louder or start to sound a little more metallic, then contact Asus directly.
