Sony's PlayStation 4 has been passed by the FCC, meaning the retail version of the console is already deemed viable for sale to the American public. Engadget reports that the accompanying documents reveal a "max clock frequency" of 2.75GHz, which gives us an idea of how much power the box is packing. What's more interesting though is the fact that the PlayStation 4's operating temperature is listed as being being five and 35 degrees Celsius, which is cooler than the PS3. While Sony's current console is meant to run between 45 and 55 degrees Celsius, if it peaks at over 60 degrees you could encounter the infamous Yellow Light of Death, which essentially reduces your PS3 to a paperweight. That's not to say there's no chance of similar issues with the PlayStation 4, of course, but it does mean that you should be more comfortable playing games during the warmer months of the year. The only other piece of interesting information is that the PS4 looks set to weigh around 2.8kg, which is significantly lighter than the original fat PS3 which was 5kg. Source: IGN
