Ubuntu – My fan is not working, no active cooling system

I am using Ubuntu 14.04 on my laptop and my fan is not working(with Ubuntu 12.04 and Ubuntu 13.10 it was the same).

Short summary of my system

Quanta TWH motherboard, Intel® Core™ i7-2630QM CPU

I follow 3 different ways to solve my problem

1. Using lm-sensors, pwmconfig and fancontrol to control the speed of my fan

First, I try to see what was happening with lm-sensors, I even could not detect my fan. Later on, forced with modeprobe Ref1 with following command line.

sudo modprobe w83627ehf-isa-fff8

It helps to get more sensors with lm-sensors-detect but they all in ALARM, I believe they are set as null because I create them artificially or not(I am not sure about what is modeprobe is doing for me)?

Here is my sudo sensors results after that process.

At that point, I try to run sudo pwmconfig. Still, I am not able go further from There are no usable PWM outputs. I stack here with this way. (My computer is not Dell)

2. Install the latest microcode for my processor

I instal the following the steps given here, thanks to @floppy for the advise.

Installing intel-microcode and microcode.ctl packages (as @floppy suggested) are help to wake up my fan, it helps to decrease CPU temperature. Fan was working quite independent from CPU temperature. It was doing some work but still not efficient at all.

Furthermore, sensors-detect is still not able to get my fan without that sudo modprobe w83627ehf-isa-fff8

3. BIOS Update

Okey my CPU temperature is lower, but still not enough to perform even for the basic applications.

I also think about to update my BIOS, but I could not convince myself it might be the reason of my problem in the beginning. I have QUANTA TWH motherbord with i7-2630qm with INSYDE QR133 BIOS. I update it with USB up-to the QR192.

BIOS update decreases my CPU temperatures around 10~15 Celcius, I do not know how and why.

I am still looking for alternative methods to control my fan, or/and force it to work at given/at the maximum rate all the time
