Thanks Jean and Guenter,
There is no /proc/acpi/fan or /proc/acpi/thermal_zone folder but, I do see
/proc/acpi/button and /proc/acpi/wakeup.
Is there any guide on how to setup the ACPI fan control?
Regards,
Dev
$sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +37.8°C (high = +70.0°C)
(crit = +100.0°C, hyst = +99.0°C)
fam15h_power-pci-00c4
Adapter: PCI adapter
power1: N/A (crit = 18.96 W)
$sudo sensors-detect
.....
AMD Family 15h thermal sensors... Success!
(driver `k10temp')

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'... Yes
Found unknown chip with ID 0x8586
....
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `k10temp' (autoloaded):
* Chip `AMD Family 15h thermal sensors' (confidence: 9)
No modules to load, skipping modules configuration.
Unloading cpuid... OK
$sudo pwmconfig
...
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
