I'm running ubuntu 12.04 on my laptop. It has an Intel® Core™ i7-3537U CPU @ 2.00GHz × 4, 8 GB ram, and an AMD Radeon HD 8730M It also has a Intel HD 4000 but i'm using AMDI have nothing else open than Chromium, A terminal, and konversation and CPU temp is 55-60 C or even more sometimes. When I run a 3D game it goes up to 80-85 and again sometimes even more. In Windows 8 tho... temp is at 54 C most of the time. Is this normal? If not, is there something I can do about it or this is strictly hardware related problem? (if it's a problem). Help?

Well, I've got a laptop with a similar config (an nvidia discrete gpu instead of amd), and used to face the same cooling issues as you until I started using TLP- which is a command line power management tool for linux. Here are the steps to isntall it :
I also use bumblebee which helped reduce my idle temps. by around 5-7 degrees, though its only for nvidia optimus laptops. I'm pretty sure there's a similar tool for amd switchable graphics.
2This temperature is absolutely normal. You should start to worry if the temperature reaches 70-80 when 'just browsing the web'.
Also keep in mind that flash applications can eat your CPU. See Hardware acceleration of Chrome's Flash plugin for info on reducing CPU usage (thus temperature height) when using flash applications.
