Fan speed rpm not appearing in sensor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Hi ,
I am using Ubuntu 22.04 in a Intel platform to fetch the Fan speed rpm
in lm_sensor. I installed the lm sensor module.

Output of sensor command:
$ sensors
Adapter: ISA adapter
Package id 0:  +31.0°C  (high = +80.0°C, crit = +100.0°C)
Core 0:        +28.0°C  (high = +80.0°C, crit = +100.0°C)
Core 4:        +28.0°C  (high = +80.0°C, crit = +100.0°C)
Core 8:        +29.0°C  (high = +80.0°C, crit = +100.0°C)
Core 12:       +26.0°C  (high = +80.0°C, crit = +100.0°C)
Core 16:       +29.0°C  (high = +80.0°C, crit = +100.0°C)
Core 20:       +29.0°C  (high = +80.0°C, crit = +100.0°C)
Core 24:       +25.0°C  (high = +80.0°C, crit = +100.0°C)
Core 28:       +27.0°C  (high = +80.0°C, crit = +100.0°C)
Core 36:       +28.0°C  (high = +80.0°C, crit = +100.0°C)
Core 37:       +28.0°C  (high = +80.0°C, crit = +100.0°C)
Core 38:       +28.0°C  (high = +80.0°C, crit = +100.0°C)
Core 39:       +28.0°C  (high = +80.0°C, crit = +100.0°C)

Adapter: ACPI interface
temp1:        +32.0°C  (crit = +105.0°C)

Adapter: PCI adapter
Composite:    +28.9°C  (low  =  -5.2°C, high = +79.8°C)
                       (crit = +84.8°C)

I could see the fan is listed in acpi device
$ cat /sys/bus/acpi/devices/INTC1048:00/fan_speed_rpm

I was not getting why the fan speed rpm not appearing in sensors list.

Are there any modules/steps  missing?

Any help or pointer will be helpful?
