But at what cost? Dutch website Tweakers.net ran two GL Benchmarks on a new iPad and an iPad 2 for five minutes each, and then looked at both devices with an infrared camera. The company discovered that the new iPad reached 33.6C (92.5 Fahrenheit), with the hottest region nearby the device's motherboard towards the bottom of the device, while the second-generation model only reached 28.3C (82.9 Fahrenheit). That means on average, the new iPad gets 10 degrees hotter than its predecessor. Now, users worry if the new iPad has the same risks as laptops, which are believed to cause testicular and reproductive dysfunction when they get too hot."
