The command given in dmesg needs to be executed as root (sudo su)
or add a file to /etc/modprobe.d :
{{{
luk...@workhorse:~$ cat /etc/modprobe.d/acerhdf.conf
options acerhdf kernelmode=1 interval=15 fanon=60 fanoff=45
}}}
(max interval is 15, you might also add fanon=[high threshold]
fanoff=[low threshold]
Read modinfo acerhdf.
