  Samsung R522 Intel Core 2 Duo 2.0 with ATI 4560 overheats running

Bug description:
  Hi,

  I tried to install Maverick 10.10 from Live CD 64 bit on my Samsung
  R522. During installation the notebook overheats and emergency shuts
  down. I managed to install let the notebook cool down and choosed
  direct installation without the "try out" option. But the running
  system still overheated! Even in idle (cpu usage around 4-10%) the
  processors temp incresed after a period of time to emergency shut down
  at 90 degrees Celsius! I checked all, the processor is idle and
  running on low frequency, fans are running. The idle temp was in the
  upper 60 degrees! Same time on Windows Vista everything was going
  well, idle temp around upper 30 degrees.

  I tried out to install the fglrx graphics driver from repository and
  now the idle temp is in the 50th. While working around 70-80. But
  still much hotter than Windows while having a lower CPU usage than
  Windows.

  Why it is still so hot? It also seems that the fans are running at
  lower speed at given temperature than in Windows. Could this be the
  problem? Running in the 80th reduces my processors lifetime.

  The standard driver (without installing fglrx) lets the system
  overheat and could damage the notebook. Even at full speed it should
  not overheat!
