Ps4 pro coilwhine problems

When I first got my Ps4 pro and fired up call of duty infinite warfare I was dishartended by the huge amount of coilwhine the pro had.

So I had the unit exchanged for another unit and this one to have tons coilwhine.

Should I keep exchange or return and wait for a new revision?

Maybe its in your electrical. Noise on your AC power.

I don't notice any on mine, at all.

No whining here either, it's like a silent fart, without the smell.
