After turning off radeon.dpm=1, the temperature at idle goes up about 2 degrees C.
However, if I then do echo low > /sys/class/drm/card0/device/power_profile echo low > /sys/class/drm/card1/device/power_profile The temperature at idle goes down about 4 degrees C -- i.e., less than when dpm=1. The k10temp is now about 62.5 degrees C at idle. The acpitz temperature is now about 62.0 degrees C at idle. These temps are still much higher than my little ASUS laptops, which idle at about 50 degrees C, but 62.5 degrees C is still perhaps 10-15 degrees cooler than when running certain apps on the same HP machine in Windows 7. The internal temps of this HP laptop were so high running Windows7 that they compromised the internal hard disk. However, I was able to relocate the internal hard disk to another bay inside the laptop where it was 20 degrees cooler, so I think I've now fixed the disk-frying problem.
