新iPad发热时的温度 33.6度，比iPad2高大约5度

We wouldn't exactly be going out on a limb by suggesting that the new iPad is Apple's hottest tablet to date -- even before Tim Cook confirmed as much earlier today. But while Apple has plenty of reason to brag about the device's sales figures, it's slightly less motivated to be forthcoming about its tendencies to create more heat. 10 degrees more, in fact, according to infrared camera confirmation obtained by Tweakers.net. After five minutes of running GLBenchmark, the site used its infrared cam to confirm what many of you have already suggested: the new iPad runs a little hot. According to the site's measurements, Cupertino's flagship slab reached 33.6 degrees centigrade (92.5 Fahrenheit), compared to 28.3 centigrade (82.9 Fahrenheit) with the iPad 2. That's certainly not enough heat to cause a tablet to spontaneously combust, but if you happen to be one of those new iPad owners that noticed a difference, you can now rest assured that your internal thermometer hasn't missed a beat.

所以到底新 iPad 是真的比较热，还是刚拿到「新鲜出炉」的 iPad 的人的集体幻觉？Tweakers.net 把新 iPad 和 iPad 2 一起拿到红外线摄影机之下比较，发现这果然不是幻觉：在跑了五分钟 GLBenchmark 后，新 iPad 达到了摄氏 33.6 度的温度，而 iPad 2 则是停在了 28.3 度。是说 33.6 度应该还不到烫手的程度才对，或许是金属的外壳让热感更明显吧！

但不论如何，新 iPad 会比较热已经是确定的事实了。准备买新 iPad 来玩游戏的朋友，记得顺便买个塑料壳的保护套来挡一下啰～

－ 33.6 度根本不会觉得热， 出发你的体温非常的低
－ 跑5分钟温度还没build up 跑 20 － 30分钟就很不同了

用了保护套会不会影响散热？会不会爆炸？

yuba

不会爆炸

温度过高会自动关机的

咋地办哩

卖套的要赚喽？

根本不是这个问题

ipad真的偶尔会变得特别热，像热水杯一样，虽然不至于烫手到拿不住，但是会很难受

水杯里面的水有多热？

可以把smart cover放到背后起到隔热作用。

真热起来，连cover一起都热了

我买了四五天了，天天都使劲用，就今天下午遇到了发热状况，难道以为今天天气热？

现在不是讨论到底有多热，关键是apple的产品这个样子，很多人接受不了。我能接受，也能理解这个问题恐怕很难解决，但是表示有小遗憾是一定的。

我很少用，一直都冰凉的。

如果我跑个3D 大游戏，大概多久能达到你说的效果？

我跑MW3 20分钟，局部（smartcover覆盖的一点）有点热，比手上温度高一些，40左右吧。没带套。

现在的问题就在于，它的发热是不固定的，我之前连着用几个小时也都没事啊，今天下午突然就好热，要是它一直这样，我也去退，但是晚上它再没这样，，，，

代会上茅房跑个赛车试试。

晚上7点用到现在，网页加视频，少量游戏。裸机，现在手掌手背测试，没觉得有异常之热啊，只是些许正常之温度而已。
现在想想真是见鬼了， 除了第一天稍有明显感觉外， 其余几天一切正常。反而倒是电池可以再给力些。。。

dalaohu

Real racing hd 2 跑了半个多小时开始温热， 大概38度的样子。
应该属于正常，可接受范围。

天气热时可能会更r热一点。 手机有时都比这更热，

补充一点， 我的这个是带着，厚套子的

水獭拿着new iPad 长期使用就有感受了。

A few hours ago we told you that some users are complaining that their new iPad is hotter than the iPad 2. The test shows it is indeed warmer than its predecessor when put on stress with just over 5°C.

Apple quickly issued a statement on the matter. Here it is:

“The new iPad delivers a stunning Retina display, A5X chip, support for 4G LTE plus 10 hours of battery life, all while operating well within our thermal specifications. If customers have any concerns they should contact AppleCare.”

So, everything is fine.

Honestly, what did you expect? The new iPad has four graphic cores and four times the pixel count (along with a new technology, which seems to require more powerful backlighting). Of course this one will be warmer than the previous one. And the difference is 5°C, not 50°C.

Really, why everyone is so surprised? I get that every Apple product is surrounded by at least one drama (most of them righteous) , but this is the phoniest of all I’ve ever heard. Did you by any chance hold a PS Vita? It’s hot, hotter than the PSP or this iPad. But no one is complaining or boiling eggs on it. Dear new iPad users, 33°C won’t hurt you fingers.

I’m just asking people to be reasonable. That’s it.

A US consumer watchdog has warned that Apple's new iPad is a bit too hot to handle.
US nonprofit product testing group Consumer Reports reported that the new-generation iPad with its more powerful processor hit temperatures as high as 116 degrees Fahrenheit, particularly when running video games.
"It does run warmer than its predecessor," Consumer Reports spokesman James McQueen said of the third-generation iPad.

"People need to exercise caution," he continued. "We are not saying it is a dangerous product, but 116 degrees can be a little uncomfortable."
Consumer reports said the new iPad got about 12 degrees warmer than the iPad 2 tablet while performing the same intensive tasks, such as videogames or downloading large files.
One rear corner of the new iPad appeared to be a hot spot.
The new iPad's battery is 70 per cent bigger than the one in the previous version, said Kyle Wiens, chief executive of iFixit, a prominent Apple repair and parts supplier.
"It still has the same battery life," he said. "So it will run hotter."
The second-generation iPad 2 had a 25 watt-hour battery while the new iPad's battery has a capacity of 42.5 watt-hours, according to a tear-down analysis by iFixit.
A Dutch tech website also 'proved' that the new iPad is warmer, with a thermal camera picture that shows the new tablet is 5.3 °C hotter than an iPad 2.
Apple did not respond to requests for comment, but prior to the release of the Consumer Reports thermal analysis issued a public statement saying that the new iPad operates "well within our thermal specifications."
Operating temperatures of the latest iPads were hot topics among Apple gadget owners at online forums.
"It does get pretty warm," a person using the screen name ShadowJeff wrote in a public chat at website MacRumors.com. "Hope Apple fixes it or something."
"My new iPad ... definitely got significantly warm, almost too warm to hold, when running on LTE," rawwave commented on Friday. "Not even doing a lot of downloads (just browsing Twitter) but having the LTE radio on seemed to cause it to get noticeably hot."

估计不是30多度这么热。如果手拿着不舒服那就是上40度了。
可能和4G/3G也有关系。

I play Infinity Blade II for 10 mins, I can feel my iPad start to warm up since I don't have case at all.
It's not comfy but it's acceptable since IBII requires huge GPU calculation.
I haven't notice anything else would generate such heat so far including watching RMVB for 2 or 3 hours.

希望凡是有过热的apple都退钱，白送一台牛排
