My PS4 Pro sounds about the same as yours did before. I have a lot of downtime this month, so maybe I'll give this a shot as well.
I'm not bothered by a little fan noise but my Pro sounds absolutely ridiculous. It so bad it really affects my enjoyment of some games. RDR2 is pretty bad, for example. It is hard to get immersed in the game due to my Pro sounding worse than a window AC unit on full blast.
I am pretty sure it has always been this bad, and I can't imagine it is all that dirty inside. There's definitely a heat transfer issue of sorts in my unit. Perhaps a thermal paste replacement will do the trick. My regular PS4's fan was never at a level where it became noticeable or distracting.
