Debian :: Overheating In Jessie - No Fan Control

I just upgraded to Jessie and my laptop, a vostro 1710, is overheating.

Code: Select allalexis1@debian:~$ sensors
    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0:       +62.0°C  (high = +105.0°C, crit = +105.0°C)
    Core 1:       +61.0°C  (high = +105.0°C, crit = +105.0°C)

[Code] ....
   
I tried to follow what is indicated here : [URL] ....

What I have done :

Code: Select all $ sudo apt-get build-dep i8kutils
    $ apt-get source i8kutils
    $ tar xvf i8kutils_1.41.tar.xz
    $ cd i8kutils-1.41/

I am on a 32-bits system so after

Code: Select all    $gcc -g -O2 -Wall -I. -o smm smm.c

then

Code: Select all    $sudo ./smm 30a3

returns

Code: Select alleax=000030a3 ebx=00000000 ecx=00000000 edx=00000000 esi=00000000 edi=00000000
    eax=00000000 ebx=00000000 ecx=00000000 edx=00000000 esi=00000000 edi=00000000 0

Finally when I type

Code: Select all    i8kfan 2 2

I get

Code: Select all    -1 2

i.e. my fans start and then suddenly stop !
