My PC makes a sound since today

Since today my PC makes a sound like the following:

You'll have to use headphones or up the volume to hear it.

It is like every 3 seconds a "dada".

Any idea what it might be?

I'd like to avoid to fumble a lot with my PC because there are some weird LARGE ventilators which I always struggle to attach again.

Is that a HDD? I tried turning up my sound but could barely hear it.

So, if it is the hard-disk, what would I look for in the data?
I got HwInfo64, which should do the job, right? Or not?

I don't see anything really bad, but I don't really know what to look for.

I tried to post the whole output, but Steam does not like that.
So I can only cut anything I (who has no idea what he is doing) think are not needed:
