My PS4 is almost 5 years old now and the fan noise has gotten pretty bad. It starts going on the second I enter a fps game, even if I’m only on the menu screen. It also gets really hot. What can I do to minimize the heat and sound?
Well this is a easy to tough answer. Easy if your the kind of person who can open up the unit and do a through cleaning to it if you can't than you need to get it to someone who can.
Not everyone can so if you never have or don't feel comfortable find somebody, as for me it comes easy but others don't have the same skills not a big deal.
You can even watch some youtube videos on how to open up the unit and clean it.
