PS4 pro strange PSU behaviour
Just a few days ago I was playing The Crew 2 on my PS4 Pro (2018) and after like 2 hours I started to hear some strange instant clicking. The game itself was totally fine, then after 30 mins I turned off the console and it was not turning on back. Just single beep and blue light for 1 sec.
I unplugged it from the electricity, left for 5 mins, it started. When I turned off again and then was not able to start it at all - same single beep and blue light for 1 sec.
Yesterday I was able to start it several times, but that sound was immediately there. Then I disassemble the console and extracted the PSU, removed all the dust which was there (not much). After that the console was starting fine and not making any noise.
But in the evening I was watching a movie on it, after 1.5 hours it started clicking again and when I turned it off, it never turned on again,
Today I made the video, now the behavior is the following: it starts fine, no noise, but when I start the game the sound is immediately there. If I exit the game, the sound gone.

Is PSU dying? Can I use the console like that (because if it is started, no issues visible at all) and should I already order a new PSU?
BTW I am pretty sure the sound goes from the PSU as I stopped the fun with my hand and the sound was still there.
Thanks in advance.
Ist dies eine gute Frage?
