========================
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.

Mine does the same exact thing! UX3402ZA model from BestBuy the I5 one. This happenes randomly. The BIOS is really messed up on mine not sure if its the cause of the fan issue or not but thats the least of my problems right now.

Mine did this before doing anything just the copy of windows it came with and nothing else done to it.

The BIOS 304 was released a day ago and it has fixed all the fan problems of my laptop. Please upgrade to the newest BIOS in MyAsus if you have similar problems.

Falcon, thanks again for your help.
