The reality is that Sony has done a pretty good job here. We'll get to the metrics in a moment, but first impressions are certainly reassuring. On start-up, the hardware is exceptionally quiet, but as you progress into gameplay, volume and heat does start to increase. PS4 also draws a fair amount of juice too - 80W at idle on the front-end menus (the "PlayStation Dynamic Menu" to give it its proper name), 95W based on in-game video playback, and around 110-120W during gameplay - that's about 10-20W more than the first release of the "Slim" PlayStation 3. Curiously though, bringing up the menu system while in-game sees another leap in power draw - up to the maximum of 140W.
So, keep it out of a glass box and it runs perfectly cool.
For PS3 FAT comparison: (Averages)
Initial Boot-up to idle XMB:
CPU: 44 °C
RSX: 35 °C
CPU: 74 °C
RSX: 65 °C
(Note: PS3 had Cell and RSX on separate dies, with seperate temps. The PS4 APU has CPU and GPU on the same die, hence the single temperature rating for the entire die.)
