second fan, low tone, makes terrible noisef

Hi,
I finished a devuan ascii installation on the notebook 4 cores,
    (which is great imho, but btw note: hibernation first failed, and I managed to fix it with two boot parameter in Grub.confing, like described here: https://askubuntu.com/questions/1081531 … o-suspend)

Now very once a while, that is I can not reproduce the error, however, then, when once started, a very very tenacious -and now after a month it is still so -, a second fan with low tone, makes terrible noise, loud enough to disturb the neighbors, and to have it impossible to work in public, at least. (Now, louder than fridge.)
So the regulation seems wrong.

It does not stop within hours, and seemingly heats up the computer by itself. Over more it is tenacious enough to survive (come back after) longer cooling periods of acpi-sleep <24h.

I remember that I had this problem with kubuntu a years ago, when I installed a then few hardware analysis programs, hdparm or so, but this hastened the problem, so the computer crashed out of over-temperature, till I switched to xubuntu. It can be I had a package such in the install list.

Now, I would like to give previously some decent diagnosis print outs, if someone told me which command lines.
Thanks in advance

Re: second fan, low tone, makes terrible noisef

Try sensors which should say something like this:

$ sensors
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage:       +1.21 V  (min =  +0.80 V, max =  +1.60 V)
 +3.3 Voltage:       +3.38 V  (min =  +2.97 V, max =  +3.63 V)
 +5 Voltage:         +5.21 V  (min =  +4.50 V, max =  +5.50 V)
 +12 Voltage:       +12.32 V  (min = +10.20 V, max = +13.80 V)
CPU FAN Speed:      1205 RPM  (min =  600 RPM, max = 7200 RPM)
CHASSIS1 FAN Speed: 1088 RPM  (min =  600 RPM, max = 7200 RPM)
CHASSIS2 FAN Speed:    0 RPM  (min =  600 RPM, max = 7200 RPM)
POWER FAN Speed:       0 RPM  (min =  600 RPM, max = 7200 RPM)
CPU Temperature:     +80.0°C  (high = +60.0°C, crit = +95.0°C)
MB Temperature:      +33.0°C  (high = +45.0°C, crit = +75.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +74.0°C  (high = +89.0°C, crit = +105.0°C)
Core 2:       +74.0°C  (high = +89.0°C, crit = +105.0°C)

That's on a desktop though so your output won't match that.

Thanks for answering,
now that the computer stayed calm for a while. When it starts rattling again stronger I will report the two states outputs here.
Thanks so far.

Re: second fan, low tone, makes terrible noisef

Hello,
now after a month it is still the same.

Friends of mine meant the hardware broke, bur I read in the sensor manual, that the problem was, too, that the hw-chip was notoriously unpredictable. Up to now I switch the computer in to standby, till it cools, with but little success. Or I earn some come "holidays" hours, after having stood the rattling trouble during some hours.


I post you some 3 tests, the two first loud, and the last one calm.
Greetings

Adapter: ISA adapter
Physical id 0:  +74.0°C  (high = +86.0°C, crit = +100.0°C)
Core 0:         +72.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:         +70.0°C  (high = +86.0°C, crit = +100.0°C)

GPU:            +72.0°C  

And this is another:

Core 0:         +60.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:         +55.0°C  (high = +86.0°C, crit = +100.0°C)

acpitz-virtual-0
Adapter: Virtual device
temp1:        +59.5°C  (crit = +99.0°C)

Other:          +47.0°C  
GPU:            +59.0°C  

And here one when it was calm:
