It might be that you somehow triggered or changed a multiplexer configuration. Do you see fan speed(s) in the BIOS ? If you do, it might well be that you have to do that once after powerup to connect a fan to the fan speed input of the NCT6776, and then you might see it in the driver. [ And, no, it is practically impossible to get the necessary information to set the GPIO multiplexer from the board vendor. AFAIK they are using GPIO pins, but which ones on which board is a mystery. ] Guenter _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
