[FadeMind]

Environment Manjaro Linux KDE X64 (unstable branch) asus-fan-control 3.8.1 (AUR)

Type: Laptop System: ASUSTeK product: VivoBook 15_ASUS Laptop X542UF v: 1.0 serial: <filter>

Fan speed in sensors is fake. Stay always as 2600 RPM even with lower speed sounds OR turn off fan too.

And now with approx 46 C I don't hear FAN work at all. Now with DEFAULT setup temperatures fan turn on for a short while only and power off again. CPU FAN value rise during next work fan. Even if it is turned off. Tested via watch sensors with 2s refresh.

EDIT after while of using AFC:

• in standard usage (not heavy load) FAN often start, work some seconds, and stop after while (default temp. set).
• default values are too high, and when FAN does not work normal idle temperature is minimum 45 - 47 (default set).
• when I set sudo asus-fan-control set-temps 40 45 50 55 59 63 65 67 then FAN work all time at lower speed and temperature idle is 35-40.

SET 40 45 50 55 59 63 65 67

I have set:

[fademind@manjaro ~]$ cat /etc/asus-fan-control/temps

Hello @FadeMind, sorry for the delay and welcome to the AFC community! :wave:

Please note that sensors are far from the AFC business. Even I personally have bad values when reading them. I am a bit confused by your posts. So what are the suggested default temperatures for your laptop model?

BTW, does the ignored null byte in input error happen to you frequently?

[FadeMind]

@dominiksalvet Ignored null byte in input is all time during call acpi_call as you see. I set safety 40 45 50 55 59 63 65 67 and fan work all time with 35 in iddle (or not after fresh start from cold). With minimum 55 (defult generic) fan started often with 45 - 47 temp. At end I just purged AFC after testing, and reported to you this model. :)

Sensors data are misleading. Max speed cpu_fan is 4800-4900 RPM. Default is 2500-2600-2800, but after COLD DOWN to 35 fan still work.

Project is great but at end ACPI FW is sensitive and buggy here (lastest fw is applied).

You can add default generic temps or 40 + your call.

On my end safer was roll back to generic kernel manage this cause fan did not start always after minimum temp.

Thanks for your time.

[dominiksalvet]

I have added the support for your model in the latest release. Run sudo gitpack install https://github.com/dominiksalvet/asus-fan-control to update and your proposed temperatures will become the default ones for your laptop, officially by AFC.

Ignored null byte in input is all time during call acpi_call as you see.

I have never seen this warning withing my scripts. If it happens to you with other scripts as well, there may be an issue on your side with your software configuration. Should it happen only within my scripts, please create a new issue on this topic and we can take a look at that (if it even bothers you).

Thank you for the contribution! :octocat: :heart: :point_right: @FadeMind
