Something's odd, with a working CPU fan the temperature shouldn't reach 92 degrees C. Unless the heat exchanger is absolutely bunged up with fluff. It's time to open the case and get hands on, Devil Fish's air duster idea is good, but do clean all the displaced dust out of the case before you put the lid back, or it'll all end up back where it started.
92 is still too hot(unless you are in fahrenheit). I found the source of my cpu overheat problem was dust/fluff clogging the heatsink between the cpu and its fan. My heatsink has closely spaced vertical fins that can only be accessed by removing the fan(4 screws and lift off). After this you can shift any dust/fluff with something similar to a cocktail stick and then vacuum up/blow clear. Replace the fan in position and then all should be well. This dropped my cpu temp by 20 degrees.
hi, sorry it took so long to get back, anyway computer is still too high in temp,tried to get case off but not possible, undone the screws all of them, cause i didnt know which ones and still cannot get case off, any thoughts
