Using a Dell latitude D620 running Ubuntu 8.10 using kernel - 2.6.27-14-generic, I can overheat the laptop in ~ 25 minutes running the program stress with the following syntax: stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M

While running the program stress I have loaded the i8k module and gkrellm to force the fan on full time. The fan is running at full speed prior to initiating the test with no load. Even with the fan still running, the laptop will shutdown after ~ 25 minutes. At start of the run with nothing running -
acpitz-virtual-0
Adapter: Virtual device
temp1: +55.5°C (crit = +126.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +56.0°C (high = +100.0°C, crit = +100.0°C)

Shutdown at -
acpitz-virtual-0
Adapter: Virtual device
temp1: +90.5°C (crit = +126.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +89.0°C (high = +100.0°C, crit = +100.0°C)

I have a HP DV1240 running Ubuntu Jaunty running kernel - 2.6.28-11-generic which is running really hot also. I haven't attempted to stress test it to determine its thermal threshold, but it gets uncomfortably hot also and the fan doesn't appear to kick nearly enough.

I'll attach a lshw of the dell 620.
