Ps4 is slowing down why?

I have had the PS4 Slim for 2 years (2018). I never had any problems with it until the PS5 came out.

It's gotten louder and slower now. I also cleaned them inside regularly, but it doesn't help.

Did you clean them from the inside too? So fan checked for dust?

Set up the database again. You can find enough instructions on the Internet. Goes fast and helps often. It also clears your console's cache. Data etc are not deleted.

Yes, everything is still loud

I've already had it twice but it doesn't work.
