If you have FSAM 7440 (and probably others too) than you have a problem with the fans. They started working when cpu temperature raises. But very often they don't stop working and there is a little jet in front of you ](*,).
Solution is very simple. FSAM 7440 has probably broken bios and on start linux kernel disables a polling of the temperatures. To enable it add this line to /etc/rc.local:
echo -n "5" > /proc/acpi/thermal_zone/THRM/polling_frequency
This makes linux to poll the temperatures for every 5 seconds. Now fans start working and stop working.
But if you think that the fans starts too often than you can change the acpi trip points by adding this line:
echo -n "105:0:85:70:63" > /proc/acpi/thermal_zone/THRM/trip_points
Now fans starts rarely but cpu is much more hotter. I don't know if long time work with this setting can make any harm to the cpu or any other component. I have worked with this trip points setting and my amilo is still in good health.
I don't take any responsibility if you burn cpu!
Changing polling frequency is completely safe :)
