lm-sensors + Asus X299 SAGE/10G

zemerdon · 10-25-2023, 12:32 AM

Good morning,

Little bit of trouble. I have a thermistor on the motherboard T_SENSOR header which is picking up no reading or output in lm-sensors but works in the BIOS (4104).

I also have the Asus fan expansion card (version 1) with 3 fans + 1 thermistor as well which also works in the BIOS but nothing in lm-sensors.

Is there any advice on how to add these devices, or a path to start trying to get Linux (Debian 11 kernel 6.1) to report readings or communicate with these headers/devices?

Any advice would be appreciated.

Code:

SENSORS-DETECT

# sensors-detect version 3.6.0
# Board: ASUSTeK COMPUTER INC. WS X299 SAGE/10G
# Kernel: 6.1.0-0.deb11.11-amd64 x86_64
# Processor: Intel(R) Core(TM) i9-7920X CPU @ 2.90GHz (6/85/4)

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): yes

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

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): yes

Probing for `IPMI BMC SMIC' at 0xca8... 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): yes

Code:

Probing for `National Semiconductor LM78' at 0x290...       No

Probing for `Winbond W83781D' 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.

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

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

Driver `nct6775':
* ISA bus, address 0x290
Chip `Nuvoton NCT6796D Super IO Sensors' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
nct6775
#----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)yes
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.

Temperatures outside of CPU, GPU and NVMe-SSDs and also fan speeds except fans on additional cards e.g. graphics cards should be measured by the "Nuvoton NCT6796D".
Unplug your additional devices (thermistor, "Asus fan expansion card") and check for changes in output of sensors command for nct6796-isa-0290.

zemerdon · 10-25-2023, 07:14 PM

Thank you for the reply,

Unfortunately no changes moving a thermal sensor from the expander card to the motherboard header either.

I had already tried to get a differential in sensor reading by moving sensors, removing sensors, removing expander card prior to posting.

looks like the kernel isnt picking anything up? im a bit lost as everything shows up in bios fine but im just unsure how to proceed moving forward, what i would need to do to have Linux start communicating with the device.

I actually feel like its not possible.

Arnulf · 10-26-2023, 01:44 PM

Try to get information about chips used in your "Asus fan expansion card" and which bus is used for communication with mainboard BIOS.
A missing bus driver in your kernel may cause this problem.
On the other hand, an unsupported hardware monitoring chip may be used.

zemerdon · 10-28-2023, 04:18 PM

Would you suggest physically inspecting the card for the chipset model and looking that up then gathering information so see if that particular chipset is supported in Linux?

The expansion card is connected via 4 pin header cable and is it a specifically an 'Asus expansion header' on the mother board for this card only.

I feel like this may be unsupported because of this.

What do you think ?
