I installed linux-image-2.6.27-1-generic via Synaptic. The results are the same as with 2.6.24-19-generic. I even updated acpid and restarted it but no effect. The temperatures are:
- after the boot (on-demand governor, showing 600MHz): $ cat /proc/acpi/thermal_zone/THRS/temperature temperature: 49 C $ cat /proc/acpi/thermal_zone/THRC/temperature temperature: 50 C - after 5 min of viewing flash in Firefox 3.0.1 in 3 tabs each tab a different flash streaming movie (cpufreq plugin showing 1.8GHz wich is the max so no throttling) $ cat /proc/acpi/thermal_zone/THRS/temperature temperature: 60 C $ cat /proc/acpi/thermal_zone/THRC/temperature temperature: 73 C Since the fan was all the time almost silent (after the boot as on heavy cpu usage with BOTH kernels and updated acpid), I got the impression that the fan speed didn`t change at all at any time. I don`t know what temperatures my Centrino based notebook can take but it is not pleasant working on hot hot plastic. Aren`ŧ there any settings on the ACPI side to control from which temperature the fan should work with full capacity and under which temeprature it shouldn`t spin at all, to be quiet? I googled a bit about this issue but haven`ŧ found anything on it. Any suggestions?
