I have tried installing Ubuntu 12.04 on my HP Pavilion dm4 3011tx and after a few minutes the fans start to work very fast and my laptop starts to heat up; The CPU temperature got up to 70 degrees and was still rising before I turned the computer off.

I installed the graphics drivers for my AMD Raedon graphics and tried switching to the integrated graphics but that didn't make a difference I have also tried Fedora and Linux Mint and they do the same thing. Can anyone help?

It's probably hardware problem, not software. Try to disassemble it to cpu/cooler level and clean the dust using can with compressed air, air compressor or similar. Dust is most often the overheating cause. If it's still overheating try to replace the thermal paste on cpu and check other components (hdd, gpu, ram...) or you could just go to a PC support store so they could do all of that.

But Its only a new laptop and I have no overheating problems in Windows 7 (should have mentioned this). – gevvek Sep 24 '12 at 8:49
Oh, then some of your hardware components may be unsupported or unstable on Ubuntu, I've seen similar problems myself. Try installing VirtualBox on Windows 7 and install Ubuntu on a Virtual machine. You shouldn't have any problems like that. Tell me more about laptop specs (CPU,RAM and stuff..)!? – Alen T Sep 24 '12 at 9:54
Laptop specs: 2nd generation Intel Core i5-2430M Processor, 8GB 1333MHz DDR3 RAM, ATI Radeon HD 7470M Graphics GDDR3 1GB. – gevvek Sep 24 '12 at 10:06
Great laptop, don't know really whats the problem with booting up Ubuntu. But install it on Virutal Box on Windows 7. It's quite easy. Just open VBox.. go to new.. follow the steps.. and install it from .iso file.. Use it like that, it's fully functional despite it's on a virtual machine. – Alen T Sep 24 '12 at 10:19
Yeah ill just do that. Thanks for your help. – gevvek Sep 25 '12 at 9:58

It's Hardware Issue.You should replace thermal Paste on processor. First clean your Surface of processor and see the post for Apply thermal paste

It seems there is a bug in Unity causing this. I've had to switch to Kubuntu because of this, it's not overheating.
