Problems with fan control

I'm having problems controlling fan speeds. sensors-detect are not finding anything about fan control.

nawi ~ $ sudo sensors-detect

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

nawi ~ $ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +57.0°C  (crit = +199.8°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +57.0°C  (high = +86.0°C, crit = +100.0°C)
Core 0:         +57.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:         +57.0°C  (high = +86.0°C, crit = +100.0°C)

nouveau-pci-0100
Adapter: PCI adapter
temp1:        +56.0°C  (high = +100.0°C, crit = +110.0°C)

nawi ~ $ sensors -u

nawi ~ $ 

nawi ~ $ sudo pwmconfig
# pwmconfig revision 5857 (2010-08-22)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

sensors is loaded at boot.

I have Intel® Mobile Core i5 2430M / 3MB L3. It's annoying that the fans are "blasting" at full speed even though the temperatures are pretty low.

The problem might be that I'm not loading a correct module for my chipset, but I've no idea what the name of the module might be.
