PS4 Pro runs under full load in PES2020, how to fix?

My PS4 Pro runs at full speed with PES20 (digital version) within about 2 minutes and sounds almost like a hot air dryer or airplane and also runs pretty hot. In the course of this, I opened the device today and removed the dust on the component surface and in the fan wheel, but this does not change the situation. The PS4 is set up horizontally and has enough space for the supply and exhaust air.

Do you happen to have a problem with that too? Is that problematic in the long run? Because of that, I haven't run out yet. I have already switched off or reduced the boost mode and all settings and extras, but everything does not work.

In the main menu of PES everything is still normal, but as soon as I start a match, it goes to full load after the loading screen and gets louder and louder. Meanwhile, I'm also a bit worried about playing happily in front of me, after all, I don't want to shoot the part.

Would it be sensible / helpful to attach several accessories?

On the one hand I'm thinking of the: Attachment fan from Elec Gear which is equipped with 5 fans. I would also put the large fan from VinCorp underneath.

Would that make sense or would it have a positive noticeable effect? Or would it just be a shame about the money?

Don't have the game. But with certain games the PS4 Pro turns up a lot.

Of course, it also makes a difference whether the room is now 25 ° C or 35 ° C.
