Fps drops on the Ps4 Pro. What can you do about it?

I gained a Ps4 pro about three months ago and have since been working in games like PUBG or Fortnite Fps-drops. Most often the fps drop to about 30 fps, but sometimes to 8 fps. What can you do about it?

I would unscrew the Ps4 and remove it. When I owned a laptop back then, I did that a lot and had more power as it did not get that warm.

I would as already mentioned unscrew the PS4 and blow out z.b. With a compressor! But with care!

And remember, if you screw up the warranty, you should still have a warranty claim.
