Ps4 clean, compressed air with aerosol?

I wanted to clean my ps4 because it's getting too loud, so I bought compressed air spray. Rear is on it but that there's aerosol in it and that should be flammable. Nevertheless, it says that it is suitable for inaccessible places in computer and office equipment. So I just wanted to ask if that's safe, thanks in advance.

Is it when the PS4 was disconnected from the mains before cleaning

Yes, sure, just do not spray on hot surfaces and of course unplug the power supply.
