Coil whine on CPU??

[Applecake]

Thought CPU couldn't get coil whine but recently been getting clock watchdog timeout for no reason system has been stable for 5+ years without issue 

 

Put the cores to 4ghz (was on 4.6) seems to be stable sometimes but other times will just bsod

 

Here is a video of the sound, microphone is put onto the back of the board where CPU bracket is 

 

This sound is not coming from gpu or waterloop listen to video

Could this noise be power delivery circuit?
