This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
 
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     Yes
Found `SMSC SCH5504-NS Super IO'
    (no hardware monitoring capabilities)
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      No
 
Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No
 
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No
 
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.

Sur Ubuntu 10.10 desktop sur lequel j'ai testé cela aujourd'hui, lm-sensor et fancontrol sont déjà installé.
Il a donc juste fallu que je détecte les sensors avec sensors-detect et que je configure avec pwmconfig.

Sur un Ubuntu 10.10 server il faut installer lm-sensors avec
sudo apt-get install lm-sensors

Ensuite on détecte les sensors avec
sudo sensors-detect
On reponds oui a toutes les questions.

On reboot pour que les modules soit chargés.
On peut tester avec
sudo sensors
qui doit afficher les temperatures et les vitesses des ventilateurs.

On configure la gestion des ventilateurs avec
sudo pwmconfig

Et on reboot encore une fois, et cette fois ci la vitesse des ventilateurs sont gérées.

Pour les réglages de pwmconfig, j'ai configurer :
Tmin 45°c
Tmax 58°c (voir les t pour cpu : http://mysite.verizon.net/pchardwarelinks/elec.htm#intel)
délai 2 sec

J'ai testé avec cpuburn (burnP6) avec cette config le CPU ne monte pas au dessus de 55°c avec une charge a 100%
