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.

Alex, I can confirm this issue is not specific to his system.
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":

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?
