Yeah.  That's just coil whine.

 

Did anything change in the last two weeks?  Like, did you buy a new fan and plug it into the same circuit or something like that?

That's why I'm asking if anything has changed between two weeks ago and two years ago.

 

It could just be that after 2 years, the lamination on one of the coils has cracked open (it's a very thin layer of lacquer).

 

Over time, the adhesive and lamination starts to break apart and the laminated layers separate from each other slightly. The vibration of these layers is the humming noise you can hear and once the adhesive starts to break, the sound gets louder.

 

Believe it or not, this happens over a number of power cycles rather than age.  A PC that's left on 24/7 is less likely to have this happen than one that's turned off and on every day.
