Clean PS4 without writing it down?

My PS4 gets mega loud while playing. Like an airplane. The ventilation is definitely full of dust, but can I get it quieter without having to unscrew it. I found a video on Youtube where a guy put his PS4 in a plastic bag, and got all the air out of the bag and then the vacuum cleaner in the bag (where everything is set up) and there was no more air in the bag inside and vacuum cleaner turned on. Would it bring anything for everyone again, here is the video

Mine is so loud too. Probably because my PS4 is the first model that came out.

Yes have mine since release

That may be the reason.
