As far as cooling systems are concerned, ASUS does have the GX series laptops (GX700, GX800) with liquid cooling systems. The main problems are: the price (easily 5-6k USD/EUR) and weight & dimensions (it's more of a 'relocatable' computer, rather than something you would carry around every day). On the other side are the GL series that seem to be designed more towards the slim looks and hence tend to have poorer cooling efficiency.
G series (especially the more powerful models) tend to be quite bulky (a 17.3" screen laptop can effectively be up to 18.5" in size) and thus have more efficient cooling. Still, you might find threads that claim that on certain models, even stock settings seem to push the CPU (mostly) way too far compared to how much heat the laptop can disperse. This applies even to the flagship G752, which is quite massive.
There's also the ASUS ROG Zephyrus with a TDP-limited GTX 1080 (a.k.a. MaxQ), claiming to deliver relatively low fan RPM even under load. Might be worth looking into it. In any case, a cooling stand is likely to be a good idea.
