Does someone knows why only NitroSense shows the rpms of the two fans of Acer Nitro 5 AN515-43. No other program in Linux and  in Windows is able to read the fan sensors and to show rpms. BIOS is latest 1.06

  • Yes! The rpm of both fans should be shown in nitro sense.

    This answer doesn't  helps at all, I know that NitroSense is showing the RPMs but why other programs cant access the sensor and read the RPMs? How I will see the RPMs in Linux then when no NitroSense for Linux is available?

    Its not Linux only, no other windows program can read the  fan speeds, tested with HWMonitor, Core Temp, Speccy, Fan Speed and no results at all.

    Good afternoon batmalin !

    Have you tried Speedfan Cool & Silent ?
    Have you tried to use the sensors command on the terminal?

    Terminal command for installation:
    sudo apt-get install lm-sensors


    See here: https://www.cyberciti.biz/faq/how-to-find-fan-speed-in-linux-for-cpu-and-gpu/

    Yes I have tried almost evreything, that`s why I am asking here. lm-sensors detects only T sensors, so for now Nitro Sence is the only sw capable to access this information and I am wondering why.

    Some models that have proprietary cooling hardware are only accessible by proprietary software as the control paths do not pass through the internal controllers or the chipset.
    If your device has this system with only low level access you can read the RPM information.

    Ok, is my system one of those models? Who can confirm? If yes why Acer made such sw for win only?

    BTW we all know that this can be enabled with a BIOS fix/update, so who can inform the engineers to address this issue and to fix it with the next release?

    This is not an official Acer support Forum and is not a line of communication to Acer although Acer moderators read this Forum to correct posts. We are a community of users trying to help each other.
    Acer laptops are already shipped with either Predator Sense or Nitrosense which serve as a cooling monitoring and control program so I don't really see them going to the trouble of a BIOS update to support a 3rd party fan monitoring system

    Well this shows only that Acer doesn`t care about anything but the profit. Thanks for the answer anyway. I will wait till next 2 bios releases and if no fix will sell all my acer hw and will never come back again.

    Sorry that you feel that way but to be truthful yours was the 1st request for this BIOS change that I've seen so it isn't a feature that has been in high demand. BIOS updates are usually few and far between and cover essential system improvements. As an example Acer did respond with a BIOS update to the Keyboard Backlight Timeout problem but there were literally hundreds of posts demanding it.

    True, but I am not asking to rewrite the enire BIOS code. Making 2 sensors accesible is not a big change. The BIOS opitions are highly restricted anyway, you can`t change anythig usefull. Leaving users with few options is not good at all.

    It`s in the setup variables of the unpacked BIOS. That`s why I have asked Acer and here number of times Acer to provide BIOS with unhidden options, in order power users to play with their own harwdare but no luck so far. I have to do it on the hard way :(.  I am ready to sign that I don`t want warranty just to be able to really own my hardware not just having a white box.
