Acer Nitro 5 AN515-42 Nitro sense CPU fan is not working.

Please help and advise what's need to be done. I'm done re-installing and tried different settings like Custom and Max even playing games. Still the CPU fan is not running or ZERO RPM. I don't know if it's normal.

    Take a needle or a very thin object and try to push the fan, as it might be temporarily stuck.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    The CPU and GPU fans are rated differently, they are normally running at different speeds. What temperatures are you seeing with each?

    The fan speeds are independent of each other and individual temperature sensors for the CPU and the GPU control fan speed. As the CPU and GPU are usually at different temperatures then so too the fans are usually at different speeds so your fans are operating normally.
