After using the pre-installed Windows Vista on my Acer Aspire 4730z for over 4 years, I decided to switch to Ubuntu. I installed a brand new SSD with Ubuntu 12.04, which I later upgraded to 12.10. Everything works fine, except for the fact that the CPU gets very hot. This problem exists under 12.04 and 12.10. It did not exist under Windows Vista.
-Idle temperature is around 55 degrees Celcius (@ about 2-3% CPU usage) -When watching 1080p video (CPU usage around 50%) it can get up to 90 degrees Celcius
My only guess is that it might have something to do with the integrated graphics (If I check under system > details, it says "Graphics: Unknown").
Other than that, I don't have a clue. Any ideas?
