The console is a little louder than a PS3 in the original version. In the old console, the fan is very loud, in Super Slim drive is the noisiest component. For a comparison with the Slim console I do not imagine, because the volume varied greatly here.
In my opinion, the console for the price is absolutely great. I would buy no PS4 because my games offer seems almost ridiculous to date and I want to wait until incorporated some changes to the hardware in the production process. As my old fat PS3 died the Hitztod after 6 years, but had a new console (if only to watch BD). An Xbox was not in question, the reasons I do not even argue out fanboyartig here. I chose the Super Slim actually only because the Slim console was unavailable. Buying I have no regrets. When watching Blu-ray movies, the drive is very quiet and barely audible, while playing it makes itself noticeable. But since I do my Dolby-conditioning never quite quietly had to enjoy an acoustic experience can, makes me do nothing. Who does not hypersensitive is as far as the volume of its devices, can access safely!
