[SOLVED] Fan control issues coretemp/NCT6793D

folkdanskung · 2024-02-03 08:06:58

Good day, I've been scouring the net to solve this but to no avail. I have a ASUS PRIME Z370-P motherboard with a Nuvoton chipset which supports pwm. Can control fans just fine in Windows with Speedfan. BIOS also has a fan control application (which is lousy and barely works).

In Arch however I cannot get this to work. I've run sensors-detect successfully, saved lm_sensors config and upon booting correct modules are loaded. See output below.

Output of sensors-detect

# sensors-detect version 3.6.0+git
# Board: ASUSTeK COMPUTER INC. PRIME Z370-P
# Kernel: 6.7.2-arch1-1 x86_64
# Processor: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz (6/158/10)

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.

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
# DMI data unavailable, please consider installing dmidecode 2.7
# or later for better results.

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

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

Driver `nct6775':
  * ISA bus, address 0x290

Upon performing pwmconfig I run into the classic error (cropped message)

/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed

From here I haven't progressed. Searched the net and found lots of people having the same error but no solution, same when searching this forum specifically.

So, I tried other paths. Found coolercontrol in AUR which seems like a good alternative. Successfully installed, enabled and started daemon, application starts but shows only a dark blue screen. Right-clicking allows the window to be refreshed, which it does, and continues to show a dark blue screen. But this is another story/post.

Do anyone have any clue on how to proceed with fancontrol here? Thanks in advance.

Best regards
Marc

I have a Z370-A. I had to add

acpi_enforce_resources=lax

to the kernel command-line to enable the 6793D. Then run

sudo sensors-detect

again.

You should get an output similar to this (without a configuration in /etc/sensors.d):

6793D output

Why do you say that? I have my fans set thru BIOS...spin-up/spin-down on demand, without having to mess with the various fan-speed apps (which may or may not work).

It did indeed work, thank you!

I may have exaggerated slightly. It is however when compared to Speedfan in my opinion, not good. Only allows three set points per fan for speed curve and minimum threshold is quite high, so I can't get my pc as quiet as with Speedfan. Maybe your version works better. Though I have been using it in lack of anything else. Looking forward to set fancontrol up properly now.

Again, thank you!

One thing to keep in mind...if you're going to use the chip to set curves up for each fan, you'll need to verify what each header on your board equates to what output of the chip (as an example, fan5 on my output is the AIO header on the mobo).
