I have got HP notebook, specifically HP pavilion dv7-3190ec, for about a year or so and I am at the moment having some (serious I think) problems with overheating. Both CPU and GPU temperature is reported about 73°C when browsing the Internet and listening to the BBC Radio 1 at the same time. Nothing really hard I'd imagine. When it comes down to doing a task more resource consuming (like playing a game, or running a virtual machine) it goes up to approximately 92°C.
I'd imagine the problem is with fan being stuffed with dust, but unfortunately I cannot access it like at all 'cos of faulty screw. Tried vacuuming it out from the outside tho that did not seem to be really effective.
Do you think such a temperature is dangerous for components inside the notebook when being exposed to it for a longer period of time (like few hours @ 90°C and then virtually all day long @ 70°C)?
Do you see any other way other than violently opening the notebook of dealing with this prob?
EDIT: The notebook is located on a table. I even tried having it 'hangin up' in air with external fan cooling the air beneath. Sounds bizarre, but I suppose not bizarre enough, since it didn't work.
Thank you,
Chester

Vacuuming is a very bad idea, generally. Vacuums create high levels of static electricity that can seriously damage electronic devices. Also, the wind speed can be quite high, and may over-spool the fan, causing bearing and motor damage.
Canned air is better for computers because it does not have the static discharge problem. However, with laptop fans, canned air can still over spool the fan, so caution must be used.

Yes, your temperatures are quite high and you have good reason to be concerned.
If you cannot access the fans yourself, you should probably take the system to a computer repair store. Laptop cleaning is usually relatively inexpensive and can be completed rather quickly. They may also be able to remove and replace the damaged screw.
