There’s a plus side to the iPad 3: you’ll always be able to reheat your favorite foods with it.
Per AppleInsider, a new analysis has found the A5X chip in the new device runs as much as 16 degrees Fahrenheit warmer than the A5 chip in the iPad 2.
According to a series of tests conducted by Repair Labs, the A5X chip registered temperatures up to 36 degrees celsius (96.8 degrees Fahrenheit), compared to A5 readings of 27 degrees C (80.6 degrees F). The experiment involved opening up the tablets in order to directly measure the temperatures of the chips.
Technicians measured multiple components inside the new iPad in order to verify that the A5X was the part putting out the most heat. The report speculated that a difference in materials between the A5 and the A5X may be a contributing factor, as the A5 is believed to be ceramic, while the A5X is “obviously metallic.”
An external test involved having the two iPads to play movies on Netflix. The third-generation iPad started at 27 degrees C (80.6 degrees F) and warmed up to 32-33 degrees C (89.6-91.4 degrees F), while the iPad 2 started at 24 degrees C (75.2 degrees F) and only climbed to 25-26 degrees C (77-78.8 degrees F).
Repair Labs said it was was unable to reproduce the 116 degree F temperatures that Consumer Reports noted earlier on Tuesday, though it did note that holding the new iPad 3 “could be noticeably warmer after only a few minutes use,” especially if held where the A5X is located.
Writing for Consumer Reports, Donna L. Tapellini said that the new iPad felt “very warm” when at its hottest, but not “especially uncomfortable if held for a brief period.” The story was quickly picked up by other outlets, some of which dubiously claimed that Apple’s new tablet could cause burns.
Consumer Reports is no stranger to controversy with Apple’s devices. The consumer advocacy group retracted its recommendation of the iPhone 4 in 2010 because it was able to reproduce a signal-loss problem in the device. With the release of the iPhone 4S last year, the group announced that Apple had resolved the issue.”
Separate tests conducted by Tested found a maximum temperature of 82 degrees F on the third-generation iPad when playing “Infinity Blade II,” the same app used by Consumer Reports in its tests.
Display expert Dr. Raymond Soneira of DisplayMate attributes the new iPad’s extra warmth to the fact that the device has approximately twice as many LEDs as its predecessor. “The LEDs give off 2.5 times as much heat as the iPad 2 and so will the battery and power electronics on the new iPad compared to the iPad 2,” he said.
An infrared test conducted earlier this week by a Dutch site found the new iPad to have reached 92.5 degrees F during a GLBenchmark test, almost 10 degrees hotter than the 83 degrees F measured on the iPad 2 during the same test.
For its part, Apple issued a statement on Tuesday that the new iPad operates “well within [its] thermal specifications” and urged customers with concerns to contact its support service.
Stay tuned for additional details as they become available.

So NOW WHAT?
I was looking to get the new iPad but this scares me. I do drawing on my iPad 1 and wanted the faster processor as well as the new screen. However, is the additional heat going to cause component failure down the road???
I hate to have to get a reduced price iPad 2 at the end of its product life BUT also don’t want to be an early adopter only to find out that I just made a mistake….
Can software or firmware updates cure these issues or are we looking at a short production run for this thing?
