Talk:Problem with fan noise
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).
