Ps4 louder than before after purge?

Cleaned my ps4. (Above the cover down and the fan cleaned. Very carefully and with cotton swabs of course, now (right after cleaning jz it was a few days ago) my ps4 has started (probably) to scrape up the speed of the fan.

Problem: Ps4 is louder than before cleaning. What should I do?

Actually, that's not what should happen. For me it was exactly the other way around, that's how it should be. You can clean them again, or check the fan again. Perhaps it is very unfavorable, there should be space above, below, in front, behind, left and right and it is best to put something under it on the sides. This cools it from below. Unfortunately I can't do more.

Thermal compound applied?

Nah, I just cleaned the fan

The ball bearings of the ventilation are defective.

Simply buy a new one or a gaming PC right away.

Thank you very much

You're welcome.
