Unless a bug was introduced here, these values either come from the chip itself, or from your configuration file, depending on whether you ran "sensors -s" or not. > How can the minimums be corrected? Setting the correct "set fanN_min" lines in the lm78-* section of the /etc/sensors.conf and running "sensors -s" afterwards should do. > Using the fan divider on fan1 and fan2 didn't help, and on fan3 the > divider is not modifiable: Fan dividers divide an internal clock, they do not alter the final speed value. > I'm also looking for a way to disable the chassis intrusion alarm > through software since no connector for it is available on my > motherboard. You can't disable it at the driver level, but you should be able to do so at the libsensors level by adding the following line to /etc/sensors.conf (in the lm78-* section, obviously): ignore alarms -- Jean Delvare
