I tried all the plugs on the motherboard. If I get the information from ASRock about how to read the fan speeds, could I make a config file specific to this motherboard? _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
