Question Slowing down fan in MSI MS-7418?


Hello

This little Atom-based unit works fine with Linux, but its fan is running at full-speed all the time.

So I figured maybe lm_sensors could ajust its speed dynamically, but "sensors", "fancontrol", and "pwmconfig" all fail to work, even though the modules required for this motherboard are up and running:

Code:
# dpkg -L lm-sensors
[...]
/usr/sbin/fancontrol
/usr/sbin/pwmconfig
/usr/sbin/sensors-detect
/usr/bin/sensors
/usr/bin/sensors-conf-convert
/etc/init.d
/etc/init.d/fancontrol
/etc/init.d/lm-sensors

# cat /etc/modules
# Generated by sensors-detect on Sun Sep  5 13:24:20 2010
# I2C adapter drivers
i2c-i801

# lsmod
Module                  Size  Used by
i2c_dev                 6500  0
i2c_i801                9420  0

# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

# fancontrol
File /var/run/fancontrol.pid exists, is fancontrol already running?

# pwmconfig
File /var/run/fancontrol.pid exists. This typically means that the
fancontrol deamon is running. You should stop it before running pwmconfig.
If you are certain that fancontrol is not running, then you can delete
/var/run/fancontrol.pid manually.
Any help appreciated,
Thank you.

What distro are you running?

I remember something like this on Ubuntu lately, and there is a fix.
Let us know what you are running and we will help you track it down.

Thanks for the help. It's currently running Ubuntu 9.10.

How comes "# sensors" says "No sensors found!" even though the "i2c_i801" module that "# sensors-detect" detected and wrote in /etc/modules is up and running (according to "lsmod")?

Maybe this compact hardware does require running the fan more often than I wished, but I just wanted to make sure nothing could be done to make it more quiet.

This is good advice. First find out if there is anything running the system hard, producing heat and calling for the fan.

As you eliminate this as the cause, I would like to know what the temps are. If sensors won't give it to you, an ugly way to get it is from the BIOS. Do a restart and go straight to Bios setup. There will be an area for seeing the hardware monitor/info or something like it. The sensor temps will be there. They aren't the live readings, but they will be pretty close.

When the computer is started from a cold start, does the fan run as fast and loud during the POST and BIOS part of the startup or does it only start when Ubuntu begins to load?

Thanks guys for the tip. I'll run htop and see if I can find some application that would explain the spinning.

Great, I see you marked this as [SOLVED]. Can you please post what you did to solve this so the next guy can read it and benefit.
Plus, I'm curious what it was.

Thanks

I haven't tried it yet, because I have other more pressing things to work on, but I'll give it a shot.
