Comment 48 for bug 488152

I have same problem with my Acer 4810TG notebook. The average temperature - is 70 degrees C. With proprietary driver - the temperature is 35-40 degrees C.

#lspci -nn| grep VGA

#uname -a
Linux 3.3.4-4.fc17.x86_64

#cat /sys/kernel/debug/dri/0/radeon_pm_info

I'd tried to use dynpm and profile (low) options, but it doesn't help me.

I am willing to help with testing of the solution. A lot of people complain about the heat when using the open driver that causes them to use the proprietary driver.
