Ps4 slim too loud despite cleaning what to do?

My playstation 4 slim I have now for a year. I have cleaned the fan anyway it is very loud when I start a game.

What else can you do?

If he shows more Laufgeräsche, it could be a "lag damage" of the fan itself.
That you have at higher speeds?

Since you can't repair yourself, if the PS is still so young, that should go over the dealer warranty.
