When your router get overheated it would never burn in flames, it would get restarted and in the worst cases .. You gotta rest the router to let it work again ... All electrical equipments are generating heat, but they are not the same .... you can't place the router for example in the kitchen and say .. it is normal.

It is like the XBOX 360, this console is one of the worst and i know someone who bought 3 of them. He is crazy about it because of some of the games, but i would never buy it or even think about it. Why do you think that this console got Hard Drive problems all over the world?

There is no good cooling system, ... the processor got 8 Cores, but no enough cooling system .. and that is why people keep on getting this problem and their consoles die on them and the most famous error that they got is .... Hard Drive Failure ... because of what? Overheating ... :)
