acpi & fan control


I run debian testing on a Packard Bell igo 5561 SK and my comp is getting really hot after some time. I'm afraid it to burn, so i have to switch it of every 4 hours.

I noticed a very slow fan activity : my fan works some seconds every minute. However, it seems its activity is not connected with heat but with CPU activity : when compiling code or opening heavy application, the fan runs fine.

I installed ACPID et ACPI & i'd like to force fan to run more.

/proc/acpi/fan is empty
/proc/acpi/thermal is empty

lsmod returns that these modules are loaded (among others):
thermal, processor, battery, fan, ac, lp, ds

I actually use the actual debian 2.6.8-2 kernel for K7

I don't know any tools or command for acpi config and to force this damn lazzy fan. Guess, the fact that fan and the directories fan & thermal onto /proc/acp are empty is not a good sign...

Well, any advice for cooling down this machine without ice cubes could be great!

it returns:
no support for device type : thermal

There is something called lm-sensors that might be use tp detect temperature pass it to acpi which takes the needed decision.

when i /etc/init.d/lm-sensors start
it return:
no sensors found

i then sensors-detect
it scanned & founds some i2c modules : vt8231 (my mothBo) and i2c-isa

i loaded these modules, restart services, even rebooted, tried to load other i2c modules following stuff i red on google...

BUT when /etc/init.d start, or just sensors, i always got this "no sensors found!".

I am wondering about this vt8231 modules. I checked on another machine where i installed the kernel source ans slocated it, but had no return....

Please help
