Fortunately, those days are now over. The 2024/2025 Asus Zephyrus are quiet for a gaming notebook. But they also don't offer the maximum possible graphics performance (fewer watts). But it is a healthy compromise

Not super loud, but this new 2024 model has a third fan in the centre of the case compared to its predecessor, which tends to make a "high pitched" noise. So on mine it's not a clean "whooosshh" which I find annoying. I have noticed this on 2 separate units, and there is also a thread on reddit about it.
