This Monday I'm taking the tower to get it greased and to see if they can remove the rest of the dust I couldn't remove.
For now, I'm using it for browsing, with a side of the case open, and I got EVEREST to monitor the temperature. Doesn't reach 80ºC.
Unfortunately, there are no resellers in town, so I can't get the grease myself. But I'll keep in mind the advices for when I am able to replace it by myself!
Again, thanks a lot.
