lm-sensors high temperatures

Good day, first time posting, excuse me if this question is in the wrong category.

I just now installed the lm-sensors package and noticed high temperatures. See down below. I'm concerned about the high temperatures of SYSTIN, AUXTIN1 and AUXTIN2. Are those temperatures normal?

Adapter: ISA adapter
Package id 0:  +43.0°C  (high = +85.0°C, crit = +105.0°C)
Core 0:        +39.0°C  (high = +85.0°C, crit = +105.0°C)
Core 1:        +39.0°C  (high = +85.0°C, crit = +105.0°C)
Core 2:        +43.0°C  (high = +85.0°C, crit = +105.0°C)
Core 3:        +38.0°C  (high = +85.0°C, crit = +105.0°C)

temp1:        +27.8°C  (crit = +106.0°C)
temp2:        +29.8°C  (crit = +106.0°C)

Re: lm-sensors high temperatures

Hello. There is a huge number of generic, numbered sensor names in the output. This might indicate the lm_sensors configuration is inadequate (possibly missing?) for your particular hardware. Consequently, the values are not properly scaled or outright garbage.

A very clear indication, that the output is wrong, is “SYSTIN” being above the water boiling temperature. Crossing 100°C alone requires large amounts of energy due to water evaporating at 100°C being extremely good at taking away heat. But also “SYSTIN” is an on-motherboard sensor, making this even less likely.

Re: lm-sensors high temperatures

You'll need to find out if there is a board-specific config out there wherein someone has corrected the values.  I had an older board that had output out-of-range without such a correction.  Have you seen the wiki page: https://wiki.archlinux.org/title/Lm_sensors

Next stop would be searching for your motherboard and lm-sensors on the web, sensors mailing list, github issue page, reddit, motherboard specific forums etc.
