I'm currently running Ubuntu 13.10 and have just installed the latest fglrx drivers successfully and after a day of use I'm finding my Dell Inspiron 15R N5010 is becoming very hot beneath the keyboard. I went to investigate and by using amdconfig in the terminal I was able to find out that my graphics card is running at it's maximum clock speed all the time (750mhz). I believe it should vary or at least clock down when not under load (which at the time was 0%). Does anyone in the community know of a solution to this problem? I believe it will not only reduce the overheating issue but improve battery life exponentially. The card currently is idling at around 90 degrees Celsius which is ridiculous for an idling card. Under Windows it used to only get up to 70 degrees on maximum load. I have tried replacing thermal paste etc and this has not solved the issue.
My system is of the following specifications:
Dell Inspiron 15R N5010
Intel i3 350m @ 2.26ghz*2
6gb DDR3 @ 1333mhz
ATI Mobility Radeon 5470 w/ 1gb DDR3 dedicated running on the latest 13.12 catalyst fglrx drivers.
500gb HDD @ 5400rpm
