Purchased in advance of NG for a reduced price. I've only had a chance to dabble in some fantastic games like Spider-Man, Horizon, God of War, Uncharted 4, and Detroit so far. The topic of noise has inspired a lot of writing. Things are like this for me: approximately seventy percent of the time, the prefix is barely heard, and occasionally the cooler starts to gather significant momentum (for instance, Otto's laboratory in Spider-Man), but then it returns to its typical state. Choke cracking is also audible, and from what I understand, it is not a warranty issue and many people have a problem; at various times, it is heard more powerfully than the cooler at minimal levels (showing the map in the same spider-man), and this occurs at a number of different points. When the cover is removed, it seems as though things are more enjoyable, there is improved air circulation, less noise is produced, but the radiator will become clogged with dust more quickly. It is not totally obvious why Sony did not add a grill on the top cover to allow for improved air intake, but they did not. According to the reviews, the newly revised version is somewhat less noisy, but the issue with chokes has not been addressed or resolved.
