To suggest most any PS4 is quiet is ridiculous to be honest, this one is no different, where I have mine has plenty enough air and I've even made sure by having a fan suck air into the area and push out the hot air the console produces.
Fact is the PS4 has always had a noise problem and a quick search online will show you tons of people complaining about it, Sony hasn't fixed that issue with the Pro. Digital Foundry even mentioned this and that the Pro is still a bit too noisy.
Have you heard an XBOX One at load compared to a PS4? I prefer the PS4, and design wise it's no contest too, but the XBOX is quiet in the same type of space but non of the two standard PS4's I've had or the Pro come close to it.
Maybe your too far away or a bit deaf, my father is an audiologist, maybe I can get you a checkup.
