Updating to kernel 5.0.0-37-generic alone did not change anything. But https://www.kernel.org/doc/Documentation/hwmon/nct6683.rst gave me the hint:
echo "options nct6683 force=1" >> /etc/modprobe.d/sensors.conf did the trick: # sensors nct6683-isa-0a20 Adapter: ISA adapter VIN0: +1.42 V (min = +0.00 V, max = +0.00 V) VIN1: +1.02 V (min = +0.00 V, max = +0.00 V) VIN3: +0.22 V (min = +0.00 V, max = +0.00 V) VIN0: +1.42 V (min = +0.00 V, max = +0.00 V) fan2: 1308 RPM (min = 500 RPM) PECI 0.0: +38.0°C (low = +0.0°C) (high = +99.0°C, hyst = +2.0°C) (crit = +0.0°C) sensor = Intel PECI PCH CHIP: +50.0°C (low = +0.0°C) (high = +0.0°C, hyst = +0.0°C) (crit = +0.0°C) Diode 0 (curr): +42.0°C (low = +0.0°C) (high = +0.0°C, hyst = +0.0°C) (crit = +0.0°C) sensor = thermal diode Diode 1 (curr): +26.5°C (low = +0.0°C) (high = +50.0°C, hyst = +0.0°C) (crit = +0.0°C) sensor = thermal diode SMBus 0: +0.0°C (low = +0.0°C) (high = +0.0°C, hyst = +0.0°C) (crit = +0.0°C) Thermistor 7: +10.0°C (low = +0.0°C) (high = +0.0°C, hyst = +0.0°C) (crit = +0.0°C) sensor = thermistor Diode 2 (curr): +42.0°C (low = +0.0°C) (high = +0.0°C, hyst = +0.0°C) (crit = +0.0°C) sensor = thermal diode intrusion0: OK beep_enable: disabled coretemp-isa-0000 Adapter: ISA adapter Package id 0: +38.0°C (high = +76.0°C, crit = +92.0°C) Core 0: +38.0°C (high = +76.0°C, crit = +92.0°C) Core 1: +37.0°C (high = +76.0°C, crit = +92.0°C) Not sure about the voltages - but fan and most of the temperatures look valid. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1858369 Title: nct6683 not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lm-sensors/+bug/1858369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
