I'm using Ubuntu 20.04 with an Asus Prime Z370-A MB
lm-sensors does not show fan speeds, and the Asus AI Fan Xpert program only works on Windows.
Is there a program that would run on my machine that would display the CPU PWM fan speed? I don't need to modify the speed, I just want to know what it is at any given moment.
Try it with your grub option set to acpi_enforce_resources=lax
From the documentation:
acpi_enforce_resources= [ACPI]
{ strict | lax | no }
Check for resource conflicts between native drivers
and ACPI OperationRegions (SystemIO and SystemMemory
only). IO ports and memory declared in ACPI might be
used by the ACPI subsystem in arbitrary AML code and
can interfere with legacy drivers.
strict (default): access to resources claimed by ACPI
is denied; legacy drivers trying to access reserved
resources will fail to bind to device using them.
lax: access to resources claimed by ACPI is allowed;
legacy drivers trying to access reserved resources
will bind successfully but a warning message is logged.
no: ACPI OperationRegions are not marked as reserved,
no further checks are performed.
/etc/default/grub and insert acpi_enforce_resources=lax into the parameter string of GRUB_CMDLINE_LINUX, IE:GRUB_CMDLINE_LINUX='acpi_enforce_resources=lax'update-grub and reboot.
