I've dealt with a lot of PS4's as I deal with them second hand as well as owning my own and upgrading to nearly every model over time except revised OG model 1200 and 7000 launch Pro. The only ones I've seen with jet engine fans are OG 1100 models and launch 7000 model Pro's and they were usually trashed by the owner.
Never had ANY problems with matte top 1200 (the revised OG model), Slim, and Pro 2nd model 7100 or latest 7200 model, they've all been absolutely fine. Honestly slims and 7200 Pro's run like a dream, very quiet.
Never had any issues with any I've owned personally too. However the ones that do have jet engines I've seen, wow that is an unacceptable noise when in person.
