eeepc 901 fan not working

Hello everyone! I installed Arch on my EeePC 901 and everything seems to run smoothly, until I noticed that the fan is not working. I did a little search on the forums, to check if someone already had to face something similar but with no success.

This is the output of pwmconfig:

# pwmconfig revision 5857 (2010-08-22)
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 is acpitz
   hwmon1/device is coretemp
   hwmon2 is eeepc

Found the following PWM controls:
   hwmon2/pwm1

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon2/fan1_input     current speed: 0 ... skipping!

There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.

This is the output of fancontrol:

Loading configuration from /etc/fancontrol ...
Error: Can't read configuration file

And this is the output of sensors:

Adapter: Virtual device
temp1:        +62.0°C  (crit = +85.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +18.0°C  (crit = +90.0°C)

eeepc-isa-0000
Adapter: ISA adapter
fan1:           0 RPM

I'm pretty a newbie and I don't know what to do, is there someone who can give me some advice please?
Thanks to all.

Re: eeepc 901 fan not working

Hey, congrats on your fresh install.
A non-working fan sounds dangerous though.
I don't own an eeePC, but there seem to be a number of packages in the AUR for those.
Have a look at this one - which sounds right to me by description: https://aur.archlinux.org/packages.php?ID=59044

Or one of the numerous wiki's here on Asus hardware has hints maybe (beware of outdated info relating to kernels <3.0): https://wiki.archlinux.org/index.php/Category:ASUS

But in fact usually the kernel autodetect should configure the fan for you.
It may help others to give you more direct input, if you post (1) your daemon array from rc.conf and (2) the output of

lsmod

. Also look in

dmesg

after boot for messages regarding the cpu scaling/fans.

edit:
I just re-read and see you already quote output from fancontrol, which maybe the package I link above.
If yes: Check if the daemon it needs is loaded (https://aur.archlinux.org/packages.php?ID=14774)

Re: eeepc 901 fan not working

Thank you for your answer, sorry but I can't check the forums too often...

The Wiki page about my model dosen't give any advice on this subject.

I installed the eeepc-fancontrol package, the daemon is running but the fan is still dead sad

Here is my modules and daemons from rc.conf:

MODULES=(rfkill acpi-cpufreq eeepc_laptop asus_eee bluetooth snd-hda-intel)
DAEMONS=(syslog-ng crond dbus acpid alsa networkmanager bluetooth sensors eeepc-fancontrol lxdm)

Re: eeepc 901 fan not working

Fan works fine on my eeepc 901 with eee-control and nothing in MODULES

Re: eeepc 901 fan not working

@lspw: It is fine to post long console output here in the forum, but use [ code ] tags instead of [ quote ] please.
That way the box gets scroll bars for the output.

You have a lot of eee-specific daemons and modules loaded there.
It'll be interesting to read if stronnag's tip gets it working for you.

Re: eeepc 901 fan not working

Tried as Stronnag said, but nothing changed.

In fact adding "blacklist eeepc_laptop" in /etc/modprobe.d/.conf is useless, the module is loaded even in that case.

I'm thinking that maybe is a problem connected with fan divisors, but I don't know how to change them since I can't find the correct section to edit in /etc/sensors3.conf and the only module noticed by sensors-detect is coretemp.

Re: eeepc 901 fan not working

I have the same problem with 1001ha. See my posts. If I run "sensors", it does not show fan. Do you have a solution?
