Hi Christophe, > If i run "sensord -i 1m -l 30m", i read this in /var/log/syslog : > Error getting sensor data: adt7463/fan1_tach_mode: Can't access > procfs/sysfs file I would suggest that you do NOT run sensord. Most people don't need it and since it is not being actively maintained, using it is usually asking for more trouble than is worth. sensord is a deamon which will poll the sensors repeatedly, and log problems when they occur. While this is fine for servers, it is usually easier for regular users on desktop/laptop systems to just run "sensors" from times to times, or use graphical frontends (xsensors, gkrellm, ksensors...). At any rate, sensord is *not* required for fan control operations (neither automatic nor manual). It is, in fact, totally unrelated (sensord is about monitoring/reporting, not control). -- Jean Delvare
