Thermal camera imagery has confirmed what iPad 3 owners already knew: the new Apple fondleslab runs hotter than its predecessor did.
The guys over at Dutch-language site Tweakers.net took an infrared camera and snapped the tablets [1] alongside each other. Both iPads were set running GLBenchmark to thrash their CPUs, and after five minutes the team took the following snap:

The new iPad is on the left. The temperature at the lower right corner of the rear - the bit you hold in your left hand - was recorded to be 33.6°C. The same place on the iPad 2 reached 28.3°C, just over five degrees lower.
That heat zone, according to a dissection performed by iFixit.com [3], is not where the iPad 3's motherboard is placed. It's a long, thin board that runs down the right side of the iPad - or the left side if you have the tablet's back toward you, as is the case with the thermal shots.

That puts the heatsource in the battery area, though whether it's a case of the battery [5] getting hot, how the iPad's casing routes heat away from the CPU, or both isn't clear at this stage. ®
