In case you didn’t know there is an online user manual for the PlayStation 4 on their website. Like every other user manual it rambles on about every detail but yes, there still are insightful details. The Basics section of the manual shows that the console will come with an overheat indicator light.
There will be a Power Indicator on top of the console; when it lights up in White it indicates the power being on, Orange would mean the console is in Standby Mode but if it starts blinking in Red, it is an indication that the PlayStation 4 is overheating.
In case you encounter the red blinking light (im glad it is not a ring) you should immediately turn off the system and wait long enough for the machine to cool down.
Previously, the PlayStation 3 didn’t come with an indicator but the Xbox 360 has been a topic of heated debate which it owes to the infamous nickname Red Ring of Death. Two flashing red lights i.e. half a Red Ring of Death meant that the console was overheating and boy was it a turn off or what.
The Xbox One on the other hand does not come with a heat indicator, instead the Xbox general manager of console development Leo del Castillo stated earlier that the Xbox One can detect overheating and cool itself down automatically.
“We don’t actually intend it to ever have to go to maximum speed under normal environmental conditions. But there is overhead,” he had said.
Well, I hope for the sake of the gaming community that both the next generation consoles don’t hit those red lights too often.
