First disable the BIOS option "Fan Always on while on AC Power".
But after that you still see the fan going on fairly loud at 47 degrees Celsius and turning off at 42 (if the environment is not too warm).
To change this behavior you can patch the dsdt tables:
__Patching DSDT tables__
The following resources were helpful:
* [http://ubuntuforums.org/showthread.php?t=1036051]
* [http://milksnot.com/joomla/windows-xp/acpi-hacking-silencing-your-laptop]
I followed the following procedure (mainly as described in the first link above):
* disassemble the current dsdt table
{{{
mkdir dsdt
cd dsdt
cp /proc/acpi/dsdt .
# disassemble it
iasl -d dsdt
# save the original
cp dsdt.dsl dsdt-orig.dsl
# now first edit the dsdt.dsl file, see below
iasl -tc dsdt.dsl
#
# update initial ramdisk
#
cp dsdt.aml /etc/initramfs-tools/DSDT.aml
VERSION=`uname -r`
update-initramfs -u -k $VERSION
#
# then reboot
}}}
