Problem with fan noise on R51 1829 L7G (ATI M9)
On my R51 the fan is behaving like this:
- > 45C -> fan on;
- < 38C -> fan off.
By using cpufreq + laptop_mode + Xorg DynamicClocks + WiFi power management, I get the fan stopped time to time, but only for 3 minutes time (transition from 38 C -> 45 C). The cooling down cycle is taking 20 minutes in the best case.
I knew about the 'ibm_acpi experimental=1' trick, but in my opinion this is not very useful since nobody can guarantee that a temperature greater then 45 C will not damage the laptop and in the same time the transition time is very short (the laptop gets hot fast without fan).

When Xorg is running, the fan is always one and pretty loud ! Setting DynamicClocks does not help
