Hi! The overheating of my HP Elitebook 8530p with Mobility Radeon HD 3650 video card has been bothering me for a while now, however, I've just been researching the issue today.

I have the same laptop (HP Elitebook 8530p) with the same graphics card (Mobility Radeon HD 3650 video card - AMD RV635) and I'm also experiencing the same issues. I've also thought the issue is with the "dust carpet" around the heat fan/sink, but it is not the case. Since I bought the laptop in Nov 2008, I had to remove the dust around the heat fan/sink every half year to keep the laptop cool (the temperature dropped around 5 degrees Celsius after cleaning), so I know this could be an issue. Only today, I managed to decrees the laptop's temperature by using the fix suggested by Pasi in bug #41762, namely switching the power_profile from "default" to "low": [root@tlinux64 ~]# cat /sys/class/drm/card0/device/power_profile default [root@tlinux64 ~]# cat /sys/kernel/debug/dri/0/radeon_pm_info default engine clock: 600000 kHz current engine clock: 594000 kHz default memory clock: 700000 kHz current memory clock: 693000 kHz voltage: 1100 mV PCIE lanes: 16 [root@tlinux64 ~]# echo low > /sys/class/drm/card0/device/power_profile [root@tlinux64 ~]# cat /sys/class/drm/card0/device/power_profile low [root@tlinux64 ~]# cat /sys/kernel/debug/dri/0/radeon_pm_info default engine clock: 600000 kHz current engine clock: 109680 kHz default memory clock: 700000 kHz current memory clock: 405000 kHz voltage: 900 mV PCIE lanes: 16 [root@tlinux64 ~] As I commented in bug #41762, the system is around ~15 degrees colder now. Alex, does this convince you that the issue is real and it should be worked on? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/748080 Title: ATI card fan is always on with opensource radeon driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/748080/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
