My fan is blowing hard, while my cpu temperature is 32 degrees

I tried a lot of things to control my fan.

Changed grub file

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi= pci=noacpi"

_

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="Linux""

Ran sensors-detect :

To load everything that is needed, add this to /etc/modules:

#----cut here----

# Chip drivers

coretemp

#----cut here----

If you have some drivers built into your kernel, the list above will

contain too many modules. Skip the appropriate ones!



Do you want to add these lines automatically to /etc/modules? (yes/NO)



Unloading i2c-dev... OK

Unloading i2c-i801... OK

Unloading cpuid... OK

Ran sensors:

acpitz-virtual-0

Adapter: Virtual device

temp1:        +34.0°C  (crit = +90.0°C)



coretemp-isa-0000

Adapter: ISA adapter

Core 0:       +34.0°C  (high = +80.0°C, crit = +90.0°C)

Core 2:       +34.0°C  (high = +80.0°C, crit = +90.0°C)

Ran sudo start module-init-tools and sudo start module-init-tools

module-init-tools stop/waiting

As you can see my fan isn't detected.

Running fancontrol gives me this:

Loading configuration from /etc/fancontrol ...

Error: Can't read configuration file

Can you help me, please? I cannot use my laptop now in class.

Thanks in advance.

EDIT

Just installed Lubuntu and lm-sensors doesn't have any problems to detect my both my fans.
