Hi Jean,
I got rid of all the Alarms now by tweaking the sensors3.conf

There are three including the one in the power supply. The big case fan

I have read about the motherboard that it has only speed control for the
CPU fan but so far I have not been able to find the control i/o for it
with pwmconfig (see output below), so I need to dig further.
Maybe I got a silent vacuum cleaner but there is a sustained/constant
noise when the computer is heated up. When the Smart Fan is enabled in
BIOS the computer is somewhat less noisy between 30 degrees and up with
2-3 distinctive steps in speeds for the CPU fan before it reaches
cruising temperature.
I will try to
- upgrade BIOS (Need to boot into Window$!!!, Grrrr....)
- set the silent chassi fan to mid or high to help CPU fan
- check air flows including heat pipe from CPU fan
- turn off Smart Fan and try to get CPU fan control to work
Do you know where to find info on how to set the target temp for the
Smart Fan feature from Linux? I know there is no support in lm-sensors
yet but it would be fun to try it out.

$ sudo pwmconfig
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.
Found the following devices:
hwmon0/device is w83627dhg
Found the following PWM controls:
hwmon0/device/pwm1
hwmon0/device/pwm2
hwmon0/device/pwm3
hwmon0/device/pwm4
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon0/device/fan1_input current speed: 0 ... skipping!
hwmon0/device/fan2_input current speed: 2410 RPM
hwmon0/device/fan3_input current speed: 1278 RPM
hwmon0/device/fan4_input current speed: 0 ... skipping!
hwmon0/device/fan5_input current speed: 0 ... skipping!
Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!

Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)?
What should be the path to your fancontrol config file
(/etc/fancontrol)?
Loading configuration from /etc/fancontrol ...
Select fan output to configure, or other action:
1) Change INTERVAL 3) Save and quit
2) Just quit 4) Show configuration
select (1-n): 2
