Yes, I have one of those ancient motherboads, but it has served
me well. But now I would like to do something about the fan. So, first
I ran the latest sensors-detect, which told me
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
Driver `nct6775':
* ISA bus, address 0x290
Chip `Nuvoton NCT5577D/NCT6776F Super IO Sensors' (confidence: 9)
Warning: the required module nct6775 is not currently installed
on your system. Check http://www.lm-sensors.org/wiki/Devices for
driver availability.
But, according to
http://lists.lm-sensors.org/pipermail/lm-sensors/2012-October/037413.html
and
http://ubuntuforums.org/showthread.php?t=1682796
it seems to be using a nct6776, which is provided by
http://roeck-us.net/linux/drivers/w83627ehf. Which one should I use?
Based on /etc/sensors3.conf in
http://lists.lm-sensors.org/pipermail/lm-sensors/2012-October/037451.html,
I setup the relevant entry in my /etc/sensors3.conf to
# chip "w83627ehf-*" "w83627dhg-*"
chip "w83627ehf-*" "w83627dhg-*" "w83667hg-*" "nct6775-*" "nct6776-*"

Using the w83627ehf module (I actually got similar results using
both), sensors tells me that:

For now I just want to look at fan2, the only fan I have connected to
the cpu fan1, which supposedly can do pwm (4 pin). Now I thought the
next step was to use pwmconfig
(revision 5630 (2009-01-29) in my case) to see if I can change the fan
speed. according to it,
Found the following devices:
hwmon0/device is nct6776 (hwmon0/device/pwm{1,3})
hwmon1/device is coretemp (hwmon1/device/pwm2)
When I let it do the test, I get that
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: 1764 RPM
hwmon0/device/fan3_input current speed: 0 ... skipping!
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!!!
Hit return to continue:
Testing pwm control hwmon0/device/pwm3 ...
hwmon0/device/fan2_input ... speed was 1764 now 1762
no correlation
No correlations were detected.
There is either no fan connected to the output of hwmon0/device/pwm3,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php)
Did you see/hear a fan stopping during the above test (n)?
What could I be missing here?
