Zenbook 14 oled fan speeds up and cpu frequency runs high in sleep mode.

System: Windows 11
Battery or AC:
Model: UX3402, 12th Gen Intel
Frequency of occurrence: Every time the laptop goes to sleep or screen turns off.

========================
Detailed description：I recently bought the new zenbook 14 oled with 12th gen i7 cpu. I set the fan mode to quiet in MYASUS and the fan is pretty quiet (~2500 rpm or below according to MYASUS) when watching youtube and running simple programs.

But when the laptop is idle and the screen turns off, the fan speeds up (to over 4000 rpm) and cpu frequency goes up to above 3000 MHz. I notice this because the laptop becomes noisy a minute after the screen turns off. And the fan and cpu data was obtained from MYASUS immediately after the laptop becomes active again.

The fan never slows down after the laptop is in sleep mode for a long time, and it will only slow down as the laptop becomes active again. I have carefully checked all running programs in the background and did not notice any suspicious process.

The laptop is new and the drivers are up to date. I have tried resetting power options / MYASUS settings / system settings but nothing worked. I wonder if there's an issue in the fan/cpu control software.

There are many applications are running background without your knowledge ,
delete possible tasks registered under task schedulers.
disable startup applications under task manager .

Thank you for your response.

I have tried the following steps but they didn't work:
I have checked all background processes and tried to disable them one by one and then went to sleep mode again. The fan and cpu still went up. The cpu usage % was low though, it's the clock speed that went up a lot.
Disabling fast startup / disabling startup apps / changing Power & Sleep options didn't work. I noticed this issue on the first day before any 3rd party app was installed. So it's likely caused by preinstalled services or apps.

The only thing that worked was disabling sleep mode and use the tradiational screensaver program in control center. As long as the laptop is awake, both the fan and cpu are normal.

So my best guess is that there's an issue with the firmware / chip drivers / windows power control / MyAsus. This issue would be easily replicable if that's the case.

Did you check using the task scheduler application? there you can see many folders are created y many applications by third-party developers and by Microsoft windows applications.
you must delete possible tasks and few tasks registered under one folder could not be deleted,
I deleted all possible tasks after I received this way


type below line in cmd and press enter
Powershell Get-ScheduledTask

and paste screenshots
