  1. System: windows 10 Home 64
  2. Battery or AC: both
  3. Model: UM433I
  4. Frequency of occurrence: constant
  5. Reset OS: no
  6. Screenshot or video: n/a


Detailed description: Regardless of the CPU usage (e.g. 5%-15%), the fan is running constantly and loudly. Even if I select the whisper mode from MyAsus, there is no effect. The room temperature is moderate (no more than 22-23C) and I am running only browsers, mail and office programs. There was a stop of the fan for c. 5-10 seconds and they it is back on.

I bought the zenbook a few days ago and I think I have the latest BIOS (301) as of Oct 2020 and I have not changed any options there.

Please help, as the fan noise is really disturbing my work!!!😕

Thank you in advance.


  • Hello nikolay,

    May I have a record of the situation?

    Thank you.

  • Hello Blake,

    Frankly I do not know what this record is - do you need some additional information? Please let me know what I should provide.

    Thank you.

  • Hello nikolay,

    I mean a video record of the issue, since sound is something we can't see through words.

    Thank you.

  • I think I found a solution - a local service guy suggested that I update the BIOS from the BIOS with the EZ Flash utility (and a flash drive) and not from Windows.

    This immediately stopped the fan and now everything seems normal.

  • Hello nikolay,

    Okay....glad to hear that.

  • Hi nikolay, Can I get a few details on how you did this? I'm rather a layman when it comes to solving issues like this. I am having the same problem with my new Zenbook.
