I'm willing to do some hacking to get it to work. There can be three reasons: * The last fan is connected to a different monitoring chip. Run a recent version of sensors-detect again: http://dl.lm-sensors.org/lm-sensors/files/sensors-detect and share the results with us. * One of the fan inputs is multiplexed (two or more fans connected to the same input.) We do not currently support this and do not plan to support it in a near feature, as we don't have the board-specific information needed to do so. * The monitoring chip driver (it87 in your case) has a bug and it should really display 4 fans instead of 3. Tell us which monitoring chip was detected, and show us the output of "sensors -u -c /dev/null". Also tell us which kernel version you are running. -- Jean Delvare http://jdelvare.nerim.net/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
