I switched from Win7 to Ubuntu and found that my laptop is getting too hot. (very hot). When I was using Win7, it was very nice, cool.
Why this is happening and how do I fix it.

There are several issues with overheating in 11.10. At least most of those are fixed in Precise (which will become 12.04). I had similar issues with all my computers on 11.10, but never since. (Never before 11.10 either).
If you really want to get into it, you can try upgrading your kernel. Or maybe you'll rather want to upgrade to 12.04 Beta 1 on the first of March. Of course, you could always download it now and try it in a memory stick or something, just to confirm that all the issues have been resolved. They should.
Assuming you have an Intel based system like my Lenovo X220 you could try appending i915.i915_enable_rc6=1
to your boot command line, which works for me. YMMV
Try dimming the screen brightness. I have an Acer laptop that will get hot if I try running more than email and a browser. Tried everything written about temp problems except a bios update. Last night I dimmed my screen brightness down to 60%, was able to burn DVD, watch full screen video, email and browser, and download a torrent. Laptop was warm, but did not get hot. Full screen video would do it in less than 5 minutes before.
I had same problem on my HP ProBook4530s (I have i5 and ATI Radeon graphic card). You should try activate "ATI/ADM proprietary FGLRX graphics driver" (post-release updates in my case).

Just might be because your laptop hasn't undergone a complete service. Just go to any laptop repair shop and give your laptop a good service... heat sync. fan gets out of order because of the garbage stuck inside the ventilator, resultantly it doesn't let the heat out of the laptop... So try this solution and enjoy...
