Detailed description:


  • CPU temperature is between 45-50 and in silent mode but fan speeds are at 4700 RPM and not slowing down. This happens only when the laptop is put to sleep and woken up. Not seeing this issue while in restart or hibernation.

  • Hi there,

    I would say it is quite normal.

    When the laptop is in sleep mode, most of the function are still working, so there will be heat generating.

    The device would be even hotter if you close the lid.

    So after waking up from sleep mode, the system temperature would be detected and the fan would spin up.

    The RPM seems fine too. 4700 RPM is not that high.

    Thank you.

  • Hi Blake_ASUS,

    Thanks for replying but this was not happening earlier also the fan keeps spinning at that speed even when the CPU utilization is not that much and it never slows down and keeps on spinning the entire time. I also checked task manager there are no heavy processes running and even the temperatures are not that high, somewhere between 40 to 45 degrees. So, I am sure there is some issue with either sleep mode or the fan driver but I am not sure what it is.

    Best Regards,


  • Hello Jaydeep,

    The system/device temperature sometime could be higher than you expected and it does not show in Armoury crate or Task manager. It is not just about CPU utilization.

    If you do have concern, you can reinstall Armoury Crate, run the diagnostic tool to check the fan, and share more information.

    Thank you.

  • Hi Blake_ASUS,

    I did exactly what you said, reinstalled Armoury Crate, and ran the diagnostic tool to check the fan, it ran just fine and displayed no errors, however after the test, the CPU temperature as displayed was 38 degrees but the

    fan speed is still stuck at 4700 RPM. Please find the screenshots

    for your reference.

  • Hello Jaydeep,

    Thank you for providing more information.

    May I know if you switch between modes, does the RPM change? or stick at 4700? or always 4700 in silent mode?

    Thank you again.
