A word of warning, though am sure you won't need it...! If pushing your PC during this hot weather you might want to keep an eye on the temp. Have just watched my CPU temp rise to 80c as I rip a film clip. Don't know if I trust the Asus Probe monitor too much but this was a good 6 or 7 degree rise on what it was reporting earlier!
Sir Radfordin there is something far wrong if you're getting that sort of temperature. At the hottest period of last year my Athlon 2500+ reached 60 degrees and that was when playing a very graphics intensive game. I would double check the temperature with the BIOS temperature and see what it says. If it goes any higher it could blow.
it will come to no harm - as the temperature rises the processor will automatically run at a slower speed. As the temperature falls things will return to normal.
Keep in mind that the onboard temperature measurement facilities are often inaccurate and may report temperatures that are too low. This is especially the case with motherboards that use a thermal sensor below the CPU to "guess" the CPU temperature. The temperature values displayed by the BIOS usually have a correction value added to compensate for this problem - but in some cases this correction value may be too low, or the sensor might not be in good contact with the CPU.
In broad terms Athlon XP 2200+ and faster processors shouldn't exceed 85 degrees.
can actually make the problem worse. The case fans are more efficient at pulling a current of cooling air over the components when the case is closed.
In extreme situations I have seen someone remove the case side and direct a hair dryer (running cold) onto the components, but that shouldn't be necessary.
I go to some fairly warm places to work, and I don't see people with the case sides off their machines. In Singapore it gets extremely warm, but nobody seems to have a problem. Admittedly, all offices and most homes are air-conditioned, but even so........
