As I made a post asking what is the normal operating tempature of a XP1800 several days ago, well today I got a responce from AMD it is lenthy and very good. I put this fresh post so that somone might get to see it.
""Hello,
Thank you for contacting AMD.
Make sure you have the VCore (Core Voltage) on the CPU set to 1.75V. As well make sure you have the latest BIOS installed on your computer.
The temperature range for Durons, Athlons up to 1GHz, and Athlon XP processors is 0 to 90c or 194f.
And temperature range for Athlon processors 1.1GHz and above are 0 to 95c or 203f.
AMD recommends setting the temperature alarm to 10 degrees less then the maximum in Celsius and 20 to 25 degrees less then the maximum in Fahrenheit.
The "normal operating temperature" of a system or a processor is a difficult question to answer. What might be "normal" for one system will not be normal for another. There are many variables in a system that will change the normal operating temperature. Case size, installed components, airflow, processor speed, power supply, voltage settings, heat sink, thermal interface material, workload, ambient air temperature, etc. all play a role in the normal operating temperature for your system and processor.
Also note that the accuracy of the thermal probe, hardware monitor and conversion from an analog signal to digital also impact the actual temperature that is being reported in the BIOS or software.
Therefore, we cannot say what should be "normal" with respect to the operating temperature. Part of the processor specifications includes the maximum operating temperature, which can be determined from the Ordering Part Number (OPN). Please refer to the processor datasheet or our knowledge base for more info on Maximum Operating Temperature. Below is the link to the technical documents, where the Ordering Part Number (OPN) can be found.

Also, please note, the max-operating temp is based on measuring the temperature Top Dead Center of the processor die. Since very few systems measure the temp at this location it is a good idea to allow for some variance when comparing this number to the values reported in the BIOS. The accuracy of the thermal probe, hardware monitor and conversion from an analog signal to digital also impact the actual temperature that is being reported in the BIOS or software.
AMD recommends to set the temperature alarm 10 degree less then the maximum in Celsius or 20 to 25 degrees less then the maximum in Fahrenheit.
Recommended are case fans one intake and one exhaust in the back of the case to provide air flow across the critical components of the motherboard. Additionally, zip tying the system cabels up out of the way of the air flow will help to keep the system cooler.""
