If you have an apple iMac you will be used to heat… those things get extremely hot… so not sure what the issue is?

It's apparently hotter (OP) than Ps3 (but considerably smaller)… are people suggesting cause its hotter that it will fail more?

That entire post could be replied to with just "Improved engineering and design since the release of the PS3 slim". Seriously, you're just spitting theory and personal analysis. Cerny and the FCC are saying other-wise.

Given the high probability of Microsoft and Microsoft apologists trying to skew the public opinion in order to impact sales of the PS4, i will be the judge of that when i get my PS4.
If then there is a problem i will be sure to let Sony hear it. Until then there is no reason to not given them the benefit of the doubt, instead of believing what random guys say in the internet.

Yeah, but doesn't the PS4 have the equivalent of a 7850HD in that APU? That runs hot, so I can't help but be impressed. I knew of the CPU specifics, which is why I only mentioned the GPU as a heat factor.

I'm not trolling at all, Just figured i would make some laugh.

I have ahard time seeing this as a problem. IF it runs hotter, I think Sony knows how to remove the heat through vents and such. They know the debacle that was the X360 launch and the failure rate of PS2, so they will want to make a clean release this time around.

Netbooks / Notebooks have a MUCH lower TDP, plus they then have an external power brick which breaks it into two different parts separating the heat.

@Ashadian Sorry I don't know if you are trying to troll me or not, so I will answer anyway ( next time put TROLL in brackets it will make it easier)

Sony are not Stupid, but they have most likely made a late decision to change the TDP of the PS4 which has lead them to make a product which has a very low consumer grade operating temperature.

Laptops are a different story as typically the power brick is providing just one power rail (12V) and they can do this at 85-90% efficiency. The power brick is external and is exposed directly to the environment. Designers can use the case to dissipate the heat with adequate potting or other methods. The higher the heat in an area the harder it is to dissipate to the environment. Laptops are not running at 250W.

While we don’t provide engineering services to Sony, we do provide these types of services to other large companies of similar size. I am a fully qualified micro-electronic engineer and have a significant development team working around me, its not like I am just making this stuff up.

My opinion is that Sony made a late decision to run with 8GB gddr5 which added to the overall de-rating of the PS4

So why did they de-rate the temperature? there is no reason to drop the usable operating temperature unless its running hot?

A typical device runs has a maximum at 45-55 degrees C.

Why would a company REDUCE this temperature if their device could work at the most commonly used ranges?

Also why would they also include asoftware cut-out when the temperature rises slightly above this?

You are still mixing the ambient temperature (inside the room, outside the box)  with the operating temperature (inside the box).

The ambient temperature of many devices is 0 - 5° C minimal room temperature to 35 - 40° maximal room temperature. But if your room is hotter than 35° C or colder than 10° C you will have other urges than playing games. ;)

The normal operating temperature of the PS4, PS3 and many other electronic devices will be higher, probably each between 40° and 60° C.
