So, I have the following values by default: pwm1_auto_channels_pwm = 1 (1 binary - fan1) pwm2_auto_channels_pwm = 2 (10 binary - fan2) pwm3_auto_channels_pwm = 4 (100 binary - fan3) Makes perfect sense since I do not have a 4th temperature reading anywhere on the system, unless you take into account the coretemp driver, which is in a different subdirectory: hwmon0 and not hwmon1 as the f71882fg driver is. _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
