In terms of the acoustic performance of the Pro, it has much more in common with the c-chassis PS4 than the Slim. We were hoping that the larger console may integrate a larger fan - typically, the larger fan, the slower it needs to spin in order to displace the same amount of heat. We've yet to put the Pro through exhaustive tests here, but we note a peak 55dB during inFamous First Light gameplay, but really it's not so much the loudness that's the issue as opposed to the pitch. The fan spins up and down and is clearly audible from across the room. Initial tests on heat again show a profile similar to the standard PS4. We'll have more on this to share later, but right now, it's fair to say that a fair amount of heat is kicked out of the rear of the unit and in common with any current-gen console, it should not be housed in an enclosed area.
