CPU Temperature Monitoring & Limits

[George Toft]

Where can I find recommended CPU temperature limits for an AMD Duron?  I
have the AMD Duron Processor 3 Technical Specification Sheets, and all
it says is "Maximum die temperature 90C."  Recognizing there is a
thermal gradient between the CPU and the temperature sensor, does anyone
have any ideas what the maximum temperature I should experience for a
healthy PC?  I have not found any concrete numbers on the 'Net.

I configured "sensors" yesterday, and wrote a script to log system load
and CPU temp over time, which results in this output:
06-17-2002 06:47:00   0.09  95.5°F  TX: 271kbps RX: 150kbps

06-17-2002 06:55:01   0.66  107.2°F  TX: 259kbps RX: 209kbps
06-17-2002 06:56:01   0.84  110.1°F  TX: 272kbps RX: 200kbps
06-17-2002 06:57:01   1.85  111.4°F  TX: 270kbps RX: 177kbps
06-17-2002 06:58:01   1.62  112.3°F  TX: 269kbps RX: 183kbps
06-17-2002 06:59:01   1.01  113.4°F  TX: 220kbps RX: 218kbps
06-17-2002 07:00:02   0.81  113.7°F  TX: 222kbps RX: 212kbps

(As you can see, I also incorporated tracking network traffic from a
previous thread as well.  This script is located on my web site.)

I then ran the machine ragged playing an AVI movie in full-screen mode
for over 1.5 hours.  The CPU temperature reached 127F and held steady. 
I set my alarm at 129F and reset (hysteresis) at 127F.  Do these sound
like reasonable values?  Obviously, cooler is better, but I don't have
$200 for a liquid cooling system.

Thanks in advance.
