This question already has an answer here:

this is my first question here, I'm a newbie. I've just installed Ubuntu 11.10 on my laptop Sony Vaio VPCEB1C5E E-Series.

The hardware is:

  • CPU: intel i5-430M
  • RAM: 2x2GB DDR3
  • SSD: Crucial M4 64GB
  • GPU: AMD Radeon HD5650M

It seems like Ubuntu super-stress my cpu or gpu because my fan is always moving fast (faster than on Windows 7 system) and the cpu cores temp is higher than it was when using Windows 7. The two cores are aobout 4°C hotter, they're at 53°C simply surfing the net with Chrome.
I wonder if there's something I can do to lower the spinning of my fan that is noise-annoying me, or understand why Ubuntu does this. The prpblem is that 'top' shows me low percentage load on cpus, just about 3%, 10%... But the cores are still hotter than they should.

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. Imagine the linked site goes down for maintenance or forever - your answer would become worthless. – htorque Nov 11 '11 at 5:37
