Max temp for your CPU is 95°C, but unlike the Athlon XP-line, the older Athlons do not have a built-in thermal diode...instead, temperature is measured by a thermistor in the CPU-Socket. Since this thermistor measures temperature under the CPU, the actual die temp. may be several °C higher - most motherboards add 10-20°C to the thermistor-value, to get as close to the actual die-temp as possible...unfortunately, this can vary between different motherboards and even different BIOS-versions.
The best way to find out whether you have a heat issue is to leave your case open and let a really big fan blow directly on the motherboard. If this resolves your issues, then it is a heat-related problem.
QUOTE Also, My BIOS reports that Fan 1+2 are running at 0RPM.....Surely this has to be wrong? The fan in my casing is running. It is possible that your fans are either not connected to the motherboard-headers(they could be connected directly to a 4-pin connector from the PSU) or that their rpm is below what the motherboard/BIOS can detect.
