Minisforum MS-01 Work Station, sensors, initial config

Table of Contents

These are my notes on initially configuring lm_sensors, specifically lm_sensors-3.6.0-10.el9.x86_64, for my MS-01.

While I much prefer obtaining temperatures and fan speeds via a board management controller (BMC), these are consumer boxes, so lm_sensors will have to do.

TODO: Might be worth a look if temps and fan speeds can be obtained via Intel ME, that will need that I re-enable my Intel ME for testing.

Why not just sensors-detect and call it a day

Like others (example 1, example 2, example 3, example 4, example 4, …), running sensors-detect and allowing it to probe ends up with sensors displaying nct6798-isa-… and coretemp-isa-… and using coretemp and nct6775 via /etc/sysconfig/lm_sensors (n.b. …75, not …98). But nct6798 needs some attention.

Example without config options for nct6798-isa-0a20

Without additional config (that happens by dropping files in /etc/sensors.d/ further down in this post), I get a load of values that are either obviously bogus, not relevant to me or both.

lm_sensors might learn about this sensor in the future, for now I want to track the speed of both fans, I’m not sure yet if fan…_pulses: 2.000 needs adjusting.

I’ll also track the 2 temperature readings that looked sane from the nct6798-isa-… I guess they are CPU and VRM but could be wrong.

I really have no use for the voltages plus I do not know if the calculations for the ASRock X570Pro4 apply to the MS-01.

CPU temperatures I want to query using coretemp but the core numbering is not quite as expected.

Used config files

Config for the nct6798

My /etc/sensors.d/Nuvoton-on-MS-01 ignores most sensors and labels two with my current best guess.

It also allows the motherbord to beep when a sensor is in alarm state.

Notes

  • For now the main aim is to collect some stats into my Check MK instance. Once I have some value history, I might revisit my lm_sensors configuration.
  • I used sensors -u nct6798-isa-0a20 and sensors -u coretemp-isa-0000 to get the label IDs.
  • CPU Spec says Max Operating Temperature: 100° C and a modern CPU will throttle when it gets too hot. So I’m leaving both coretemp defaults of temp…_max: 100.000 and temp…_crit: 100.000 as is.
  • I might adjust temp7_max: 80.000 of nct6798 in the future.
  • Having no use for the WiFi adapter, it is disabled. No wonder there’s no temperature reading.
  • I’m unsure what acpitz-acpi-0’s temp1 represents, inlet temperature would be realistic, the shelf where it is placed is warm and it is about the same value I get from one of my Shelly H&T Gen2 when placed on top of the MS-01.
