HP mini 5103 FAN does not stop

[Member Zdenek Kincl]

Hi Guys, I installed antiX-21 Grup Yorum 32-bit version on my HP mini 5103 laptop and looks like that there is some issue with FAN control as it never stops even without CPU work… It looks like that it is regulated to low RPM at startup (booting, log-in), after some time (usage) with higher CPU load RPM increases correctly but never go back to low RPM even there is no CPU load. Then CPU is cool down to 35dC which I think is unnecessarily low.

It is also strange as I can see 1GHz clock freq for CPU, but Intel Atom N550 should have maximum clock 1.5 GHz.

It seems that some virtual sensors below do not change at all (temp2, temp4-6)

Do you know what could be a problem and how to solve it? What are the target temperatures for this CPU?

Functional keys (backlight, sound intensity, etc.) are more or less functional.

Thanks in advance!

$ sudo pwmconfig
# pwmconfig version 3.6.0
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

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

This kind of problem and the below error line is found across distros and on a wide range of hardware
but it looks like different hardware may well need different solutions.
Please search
There are no pwm-capable sensor modules installed

Which of many suggestions a search reveals will work on your actual hardware can only be
found by a person in posession of the actual device or same model. Which leaves you in the hot seat.
Info on Mint Ubuntu as widely used Debian derivates may be most helpful.

Hi [Zdar a silu najdes v syru!], I suggest to examine setting in BIOS as well.
https://www.techwalla.com/articles/how-to-change-the-cpu-fan-speed-in-bios

I had an issue (random freezing of the PC) on my workstation with AMD-Ryzen CPU and changing BIOS setting seem to have/might have solved it.
