Unlike forcing the other chips' ids, with force_id=0x8721 PWM control seems to work reasonably, with pwm1_enable=1, pwm1=0 yields around 1132 RPM on the CPU fan, and pwm1=255 yields around 3260 RPM. Should pwm1=0 actually stop the fan? I get what (empirically) seem to be consistent logarithmic increase in RPM when increasing pwm1 value, anyway. But the sensors values read with 'it87 force_id=0x8721' don't seem ok, I get this (first 'it87 force_id=0x8721', then 'asus_atk0110 new_if=1', which seems to provide good readings): it8721-isa-0290 Adapter: ISA adapter in0: +0.95 V (min = +2.78 V, max = +1.14 V) ALARM in1: +1.50 V (min = +0.00 V, max = +3.01 V) in2: +1.88 V (min = +2.66 V, max = +2.27 V) ALARM in3: +2.05 V (min = +2.68 V, max = +0.67 V) ALARM in4: +2.03 V (min = +3.04 V, max = +1.42 V) ALARM in5: +3.05 V (min = +3.04 V, max = +3.01 V) ALARM in6: +2.05 V (min = +2.77 V, max = +1.87 V) ALARM 3VSB: +6.07 V (min = +1.10 V, max = +4.56 V) ALARM Vbat: +3.34 V fan1: 3292 RPM (min = 10 RPM) fan2: 0 RPM (min = 10 RPM) ALARM fan3: 0 RPM (min = 13 RPM) ALARM temp1: +33.0°C (low = -65.0°C, high = -10.0°C) sensor = thermistor temp2: +40.0°C (low = -19.0°C, high = +127.0°C) sensor = thermistor temp3: -128.0°C (low = +119.0°C, high = -2.0°C) sensor = disabled intrusion0: OK atk0110-acpi-0 Adapter: ACPI interface Vcore Voltage: +0.95 V (min = +0.80 V, max = +1.60 V) +3.3V Voltage: +3.34 V (min = +2.97 V, max = +3.63 V) +5V Voltage: +5.13 V (min = +4.50 V, max = +5.50 V) +12V Voltage: +12.11 V (min = +10.20 V, max = +13.80 V) CPU Fan Speed: 3276 RPM (min = 600 RPM) Chassis Fan Speed: 0 RPM (min = 600 RPM) CPU Temperature: +33.0°C (high = +60.0°C, crit = +95.0°C) MB Temperature: +40.0°C (high = +45.0°C, crit = +75.0°C) This is on an Asus M5A78L-M/USB3 mainboard. t' > > Thanks, > Guenter > > Signed-off-by: Frank T.
