Hey!!!

Try this code. It tests the fan voltage controls and let's you know what's what:

sudo pwmconfig

hi, I did it and my result is

 
# pwmconfig revision 5770 (2009-09-16)
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

I think it isn't a good result ahah xD
thank you for the help

Aww man!!!! No problem

I've posted a new thread asking for any method by which you can test and access the fan controls via a Terminal or a program...hope I get some answers there...

What's the problem?.... You have a fan issue too?

Ok....try this. Log in to a terminal and:

cd /proc/acpi/thermal_zone/

I think you will find a single directory in there. Change into that directory by typing:

cd <directory_name>

Replace <directory_name> with the name of the actual directory.

then enter:

cat cooling_mode

Tell me what you see.
