I was playing around with a 4G LTE model at the local Apple Store and those iPads are turned on and plugged in and already running as hot as they can. I played one of those high resolution games and there was a section that ran hotter than the rest, but as i played the game, it didn't generate any amount of heat that I thought was unbearable at all. It was just a little warmer. Not a big deal.
I wonder if the so-called problem is worse on a 64 GB version due to the increased amount of memory. Other than that, i don't see any problem with these new systems.
I've noticed it runs hot in the lower left corner, especially when plugged in. I'm assuming Apple is 100% aware and signed-off as a trade-off to the beautiful screen. It is definitely a compromise. I've love the fact my iPad 2 runs so cool
The next rev should take care of the heat as they dramatically shrink the internal components (LTE chipset, A5X, core memory, RAM, efficiencies in the display). The internal efficiency gains should be dramatic
Now I understand better why Apple did not increase the CPU clock speed or go 4-core. They did everything possible to get the screen out the door
(Late edit...my rant isn't directed at the author of the previous post...I actually agree that Fahrenheit is quaint. But...)
You use Celsius? Let me worship you like the temperature-knowing god that you are. I've met many..."non-Americans" who inexplicably take pride in the fact that they use Celsius. I understand that the entire world using the metric system is ideal for education and science, but...
...please tell me...for those of us who are not scientists (you know, ninety-nine percent of the world), what does 0 tell you that 32 doesn't tell me? I've met Brits who quite literally look at their stupid smartphone to gauge temperature, and then suddenly wax intelligentsia about how superior Celsius is and how stupid Americans are for using Fahrenheit...as though using Celsius told them anything more than using Fahrenheit told me, and as though they had any choice in the matter what was taught to them when they grew up. Seriously, they look at their phones and feel smug about the fact that it says 25 instead of 77. ...No, you're right, this Obviously confers an enormous advantage and if I wasn't such a fat, stupid, lazy, litigious American, I'd have figured that out. If my phone had said 25 C, I'd have known to pick the white t-shirt and not the blue one.
Being pompous over something as ridiculous as a fixed scale is a sign of a lack of intelligence, not the opposite. When I begin my work as a climatologist or chemist I'll promptly convert to Celsius. Should take all of a few hours to adjust.
I don't think there's any doubt that this will become an issue. Some people are always looking for something to bitch about and will latch onto this. Just look at some of the snarky comments in this very thread. Soon we'll have the Apple discussion forums thread "views" counters proclaiming this a major issue. Then comes the "in depth" investigations by c|net for example, and of course the obligatory class action lawsuit filed by somebody claiming their iPad "burned" them.
So yes, "heat-gate" is coming and you can take that to the bank.

You are right, metric is better for science but imperial is better for everyday life. What you want out of your measurement system, is to help you grasp a quantity is without having to see it. Relating that quantity to solid objects like a certain number of feet or stones does the job better than relating it to imaginary things like meters.
That bottom-left corner (bottom right in photo) definitely gets warm to the touch. The simple solution is to rotate the iPad 180 degrees.
I'm surprised that it's only 10 degrees Fahrenheit. I had never noticed the previous iPads getting warm and this one can get uncomfortable.
10° is a big difference especially that it get so close to the upper limit of the parameter set by Apple. I fear playing graphics intensive games or even movie watching will cause the iPad to overheat and shut itself down.
Is this something that only happens to a small number of units? Mine always seems cool to the touch. Seriously. I usually have the 'smart cover' over the back, but after I use it for a while and close it the back is pretty cool. Like that cold metallic feeling.
You guys are more read than I, but everything I've looked at with the new ARM (been studying their architecture) and even Nvidia chips document that they use less power, by significant amounts than the previous versions. Even with more cores added both on the CPU and GPU. How can this be true if people are saying that the 2 extra graphics cores are making the iPad "heat up"? Getting warmer would mean consuming more power. I think...
I would like to see a FLIR (great company by the way) image of a Tegra 3 being 'bench tested'. If it has both 4 CPU cores and 4 GPU cores, plus a 5th (downscaled) core, then i would imagine it would be burning hot by FLIR standards. Heck, I've read some apple hate comments saying the Tegra 3 has 12 cores and all the bench marks are faked... (totally wrong BTW).
I may be wrong, but I don't believe it's the new processor. I love reading your thoughts though!
Note how it was determined - they ran GL Benchmark - which puts the GPUs to the maximum test. They are stressing the heck out of all four GPUs, so the heat generation is undoubtedly greater than the normal user would see. If you are doing something that stresses the GPU (action games, perhaps), then you might see it getting warm.

It ran the warmest during the very first use as it was charging in the dock and installing gigs and gigs worth of data, music and apps.
It's certainly warm, but I wouldn't say hot.
Since LTE uses more energy than WiFi (as shown by shortened battery life), then using LTE would cause it to get warmer. However, the effect is probably considerably smaller than stressing the GPU cores.
It's the display's pixel/backlight driver circuitry making most of the heat. The circuitry is usually located at one edge of the panel that has the connectors, which in this case, the left side of the iPad.
Turn down the brightness setting (like under 70%) and there will be no heat.

Water freezing is an easier concept for a Canadian to understand than boiling water is
Tegra 3 features a low performance GPU that is sub iPad2 level. The current iPad is even a bigger beast. Performance brings heat. However, you always have the option of buying Android garbage that runs cooler if that is what matters to you.
I had no idea that the new A5X was so much better in GPU performance compared to the Tegra 3.
Thanks.
I wonder how it fares in pure number crunching, like for use in a gigantic spreadsheet?

You guys are talking nonsense. As a Brit, it's painfully (at times) obvious to me that we feel comfortable with whatever random units people are using when we grow up, it's not at all about what "feels right" or whatever, just learnt behaviour from your environment. Be glad you're not living in half-metric land. We Britons are truly fucked
For example, I:
? Have no concept of what a "pound" is other than £, for body weight is in Stone. Scales are all in Stone, so I weigh, for example, 13 1/4 Stone. What this means in pounds/ounces/kg I seriously have no idea off the top of my head.
? Measure all cooking in grams, no idea about ounces/pounds really except a pound is about half a kilo (eg. in beef) like a pint is half a litre (568ml is remembered due to beer). Though mainly use ml in cooking, want my pint of milk or beer.
? Measure distance in meters, then miles \ - Know that a yard is 90cm roughly, never use it though and find it confusing that road signs tell me how many yards something will be in, just because we use miles & mph.
? Know my height to be 5'11" (is that written right?) and 180cm, but generally measure stuff in cm, feet and meters. 4 inches of snow. 2 feet of water. 2cm bezel. 9mm thin.
It makes sense, it just doesn't make sense. Be glad you're all imperial. Or, frenchies, be glad for your metricyness. We'll be using the British Standard of grams, kilos, pounds, stone, meters, feet, miles, inches, centimetres, millimetres, yards, centigrade and Fahrenheit
Why not? All those people who get erections over the number of cores or how much memory their hardware has have to pay the price sometime, might as well blame Apple
Thermal imaging of a side-by-side comparison of the third-generation iPad and the iPad 2 found Apple's latest tablet running 10 degrees (Fahrenheit) hotter than its predecessor. ...
I find it kind of offensive that the story is from Belgium, and yet every tech blog in the world is taking the time to translate the story into fahrenheit when in fact no one in the entire world even uses fahrenheit except the USA and celcius has been the standard for thirty to forty years.
Most people alive today have never used fahrenheit or even know how to convert to it.
It's 5.3 degrees warmer, not 10.
Edit: I didn't realise that people were already arguing about this.
Apologies for fanning the flames, but this article started it by reporting the whole thing in fahrenheit.
Why people are always trying to make things up when it comes to Apple?
The test with GLBenchmark is basically stressing the GPU so why a hell is it surprising that you measure higher temperatures for a GPU with two times the number of cores. A5 and A5X are both built in 45 nanometers so it's just physics that the A5X GPU runs hotter. What's surprising? It is of course designed to sustain higher temperatures and you make sound that the difference is higher by using Fahrenheits instead of Celsius (by the way why can't US just use SI units?). In Celsius it is a mere 5ºC difference. Again given the vastly more GPU resources in the A5X, those are completely predictable results.
Look here, the comparison between A4, A5 and A5X, the GPU inside the A5X is massive. This beast creates heat when you ask it to sing.

It tells me that water become ice, while the 100 tells me that water become air, you know, that water is funny it also tell me that 1 cubic decimeter of water (10cm*10cm*10 cm) equal weight of 1 kg. Since we live on the planet 90% made of water this make sense to me.

No mystery at all. It is entirely correct for an "author" to use the local unit of measurement. AppleInsider = American website. Notice that there is no second level domain after appleinsider.com (e.g. appleinsider.com.au).

This same issue was reported with the iPad 1. It was a non-issue.

Likely it depends on various factors, like what the iPad is doing at the time. This test may have been at "idle".
