Detailed description:I just want to share the fan speed info of my zenbook duo 14 pro 12th Gen in order to know the normal revolution per minute of my laptop. My CPU fan speed in stanrd mode is 4770 RPM and GPU fan speed is 5208 RPM. I don't know if it is good or bad when the two fans speed are slower or faster.


  • Hi FongPoui:

    Thank you to reach us, please provide more scenario to judge your fan speed.

    →Is this screen shared under system idle?

    →How is the speed when you boot up to system at beginning?

    →What's your battery mode at that moment?

    -Under system idle? I don't understand what it exactly means. I just captured the fan speed section from MyAsus app. At that time, I didn't run my Unreal Engine 5.

    -How is the speed at begining?

    It turns around those numbers: CPU upper than 4000 rpm, GPU upper than 5000 rpm. I don't know it is normal to have these numbers. Because by the misjudgement of MyAsus App fan diagnosis, I got once the left fan changed by Bangkok Asus technical team at home and after the system diagnosis at BIOS, he didn't say anything if these numbers were normal or not, so I don't know if these rpm numbers are normal.

    -The battery mode at that moment is Battery health charging (at 80%)

    The pictures below were captured after running my Unreal Engine 5 project.

  • Today fan status at begining...

    The tech team has confirmed the pictures you provided, the cpu and gpu fans will provide different speeds according to the current operation of the system, and your fans are working well. Please don't worry. Thank you.
