Ubuntu – Fan control with nct6796d on Asrock J5005-ITX. Can’t load nct6775 module

driversfankernellm-sensorssensors

I'm trying to control fans connected to my Asrock J5005-ITX motherboard. I've already identified that it contains Nuvoton NCT6796D chipset responsible for that. I'm stuck where I want sensors-detect to detect it. From this linux driver file I learnt that I need to load nct6775 module. Unfortunatly something is not right:

userName@Server:/$ sudo modprobe nct6775
userName@Server:/$ sudo sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# Board: ASRock J5005-ITX
# Kernel: 4.18.0-25-generic x86_64
# Processor: Intel(R) Pentium(R) Silver J5005 CPU @ 1.50GHz (6/122/1)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y

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): y

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): y
Probing for `IPMI BMC KCS' at 0xca0...                      No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No

Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): y
Found unknown SMBus adapter 8086:31d4 at 0000:00:1f.1.
Sorry, no supported PCI bus adapters found.

Next adapter: i915 gmbus dpb (i2c-0)
Do you want to scan it? (yes/NO/selectively): y

Next adapter: i915 gmbus dpc (i2c-1)
Do you want to scan it? (yes/NO/selectively): y

Next adapter: i915 gmbus misc (i2c-2)
Do you want to scan it? (yes/NO/selectively): y


Now follows a summary of the probes I have just done.
Just press ENTER to continue: y

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)y
Successful!

Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/kmod start'
to load them.

Unloading cpuid... OK

The module is not found. What am I doing wrong?

  • As I knew the nct6775 is what I want actually so I just skipped the step with sensors-detect and put that module manually into the /etc/modules. After restart sensors command displays fans and their speeds. I can now configure my fan curves.
