I have an ASUS L2400D with an Athlon 1600+ and my processor was always running
at 80°C, sometimes, the temperature rose to 90°C. And my laptop is always in
good health.
nicolas@conchita:~$ cat /proc/acpi/thermal_zone/THRM/trip_points
critical (S5): 109 C
passive: 90 C: tc1=1 tc2=4 tsp=300 devices=0xcefe99c0
active[0]: 70 C: devices=0xcef29620

I never succeed.

I installed athcool (apt-get install athcool) and now it runs at 65°C.
Moreover, I installed cpufreqd and the temperature falls to 50-55°C !
