Zenbook 2024. Heating and Thermal Throttle

Daddino
Star II

I have a Zenbook 2024 OLED with an Intel Core Ultra 9 185H. My issue is that the CPU reaches 100°C after just 5 seconds at 100% load, even when the ambient temperature is ZERO°C and the laptop is elevated to allow for better airflow. The chassis obviously feels freezing cold, but the throttling is exaggerated: even at 0°C, after a few seconds at full load, the CPU stabilizes at around 2800MHz and the temperatures at around 80°C.
Naturally, at normal temperatures (around 20°C indoors), the situation worsens further.
After speaking with another user who has the same laptop with the Core Ultra 9 185H, it seems that their device doesn't behave this drastically. (I’m attaching test photos taken at 0°C).
Is there a specific test I can run to get precise reference values? To measure CPU usage, clock speed, and temperatures... so I can figure out if my laptop has an issue before sending it in for service?

I understand that a Zenbook is not designed to dissipate a lot of heat, but my situation is somewhere between scary and ridiculous, isn't it?
Is there anyone with the same notebook who can provide me with some reference points?

Thank you everyone

@Daddino 
May I know the complete model of the laptop you are using?
Have you updated the BIOS and system version to the latest versions? 
I have sent you a message; please record the log via the method mentioned in the message and provide it to me. 
I will forward it to the relevant department for further assistance. 
Sorry for any inconvenience it may be caused. 

Thanks for replying,
the model is UX3405MA and BIOS version is 309
I believe everything is up to date including drivers and Windows 11.
