Hi, As I did not found a way to post my report/query/quesion to a lm-sensors forum, I send them to this mail address. So I would like to report how I succeeded in making lm-sensors to work with my pretty old PC, as well as to ask to improve the lm-sensors package. My PC is a MSI barebone called MS-6232 including the MSI motherboard called MS-6535. You can find details in the manual available in http://www.msi.com.tw/program/support/download/dld/spt_dld_detail.php?UID=134&kind=4 The barebone is small so the fans are too (one for the CPU, two for the box). Without any software, they are managed by the BIOS. They spin 6300-7000 rpm when the CPU temperature reaches 57C and get slower to 2900-3400 rpm when the temperature falls down to 44C. The problem is the normal working temperature is around 50C. So once the fans are triggered to the full speed, they run fast and are noisy for a VERY long time. The 2 fans speed seems to be very correlated. There are 3 possible speed states : low, medium, high. I have not investigated to replace the CPU fan (calloducs are magic), but I guess it is difficult to find one to fit to this small box. So it is VERY important to get lm-sensors to work ! The encouraging thing was that the windows program SpeedFan works fine. I have not found any information through google concerning lm-sensors working directly with this hardware, so it is why I consider my post could interest some people. My distro is Mandriva One 2007 installed on the harddrive. I setup the package lm_sensors-2.10.0-5mdk but I did not succeeded in making it to work, so I downloaded the latest source package v2.10.2. I unpacked it the run the recommended following commands for kernel 2.6.x: make user make user_install But I noticed that installed scripts were not updated so I run the following commands from the unpack directory with root rights to do it : cp ./prog/detect/sensors-detect /usr/sbin/ cp ./prog/detect/i2cdetect /usr/sbin/ cp ./prog/dump/i2cdump /usr/sbin/ cp ./prog/dump/i2cget /usr/sbin/ cp ./prog/dump/i2cset /usr/sbin/ cp ./prog/dump/isadump /usr/sbin/ cp ./prog/dump/isaset /usr/sbin/ cp ./prog/init/lm_sensors.init /etc/rc.d/init.d/lm_sensors cp ./prog/pwm/fancontrol /usr/sbin/ cp ./prog/pwm/pwmconfig /usr/sbin/ cp ./prog/sensors/sensors /usr/bin/ Then I run sensors-detect and the sensor W83697HF is detected. The following recomendation is displayed : /etc/modules.conf: #----cut here---- # I2C module options alias char-major-89 i2c-dev #----cut here---- To load everything that is needed, add this to some /etc/rc* file: #----cut here---- # I2C adapter drivers modprobe i2c-sis96x modprobe i2c-isa # I2C chip drivers modprobe eeprom modprobe w83627hf # sleep 2 # optional /usr/bin/sensors -s # recommended #----cut here---- So I respected the recommendations and I put the "modprobe" commands in /etc/rc.d/rc.local Then I could read sensor value with the sensors command and with ksensors. But when I run pwmconfig, no correlation with fan speed was detected. After many tests, I found that the following manual commands allowed the pwmconfig script to find a correlation : modprobe -r w83627hf modprobe w83627hf reset=1 Then the command fancontrol is effective to modify the fan speed. So I modified /etc/rc.d/rc.local with adding the "reset=1". But when I reboot, the fan speed is not managed by fancontrol. So I noticed that the service lm_sensors is started. By editing /etc/rc.d/init.d/lm_sensors I understood this service consists in loading modules listed in /etc/sysconfig/lm_sensors.conf and running the command sensors. So modules were loaded once with service lm_sensors at runlevel 3 then "reloaded" by /etc/rc.d/rc.local (that is run after every other service runlevels). But the module w83627hf were actually loaded once without the parameter "reset=1", so the fancontrol was uneffective. I deleted everything concerning lm-sensors in /etc/rc.d/init.d/lm_sensors and added "reset=1" in /etc/sysconfig/lm_sensors.conf. It did not work. Finally I get fancontrol to work with doing : - I modified the script /etc/rc.d/init.d/lm_sensors to load explicitly (and dirtily) the module w83627hf with the parameter "reset=1" after loading everything included in /etc/sysconfig/lm_sensors.conf - I deleted w83627hf in /etc/sysconfig/lm_sensors.conf - I disabled the lm_sensors service in every runlevel in drakconf - I created the file /etc/init.d/fancontrol as it is described at http://www.ubuntuforums.org/showthread.php?t=42737 and modified the file to make it to work in mandriva. - I added the following commands in /etc/rc.d/rc.local: service lm_sensors start service fancontrol start - I get a input error with fancontrol so I needed to modify the file /etc/fancontrol: INTERVAL=10 FCTEMPS=hwmon0/device/pwm1=hwmon0/device/temp2_input hwmon0/device/pwm2=hwmon0/device/temp2_input FCFANS=hwmon0/device/pwm1= hwmon0/device/pwm2=hwmon0/device/fan1_input MINTEMP=hwmon0/device/pwm1=60 hwmon0/device/pwm2=60 MAXTEMP=hwmon0/device/pwm1=65 hwmon0/device/pwm2=65 MINSTART=hwmon0/device/pwm1=5 hwmon0/device/pwm2=0 MINSTOP=hwmon0/device/pwm1=0 hwmon0/device/pwm2=0 To improve the package, my suggestion is: - modify the install script to automatically update the installed scripts - modify the recommendation not avoid double-load of modules - modify the script ./prog/init/lm_sensors.init to make it compatible with the syntax <module> <parameter> in /etc/sysconfig/lm_sensors.conf In order to get less noise earlier at the boot time, I tried to move the lm_sensors and fancontrol services from /etc/rc.d/rc.local to any previous runlevel. The result is that temperatures are read, but fans are not controlled. So my question is : Is there any service that must be run before fancontrol ? Kind Regards.
