It can't be that since I only reach max 92 cel which is normal for gaming laptops.
Normal? No.
While that may not be considered "HOT!", it is very very warm and not normal.
True. Your one-off anecdotal example does not set the rule. Of course there are always exceptions but exceptions don't make the rule.
It is just a simple fact that notebook cases do not have the physical space to support 3, 4, 5 or more large cooling fans (let alone alternative cooling solutions like water cooling). Notebook cases don't have the physical space to support big CPU (or GPU) heatsinks and big (width AND depth) CPU fans. And of course, notebook cases cannot
easily be opened up to totally expose the interior for thorough cleaning of heat trapping dust.
The simple answer to your convoluted "reasoning" is that laptop components run in the sweet spot for efficiency.
LOL Yeah right! And PC components don't? Now that's convoluted (and totally incorrect) reasoning. Notebooks, for sure are superior in two key areas. (1) Mobility. And (2) throttling back in performance when they get too hot.
The other thing is that laptops tend to use more exotic cooling solutions like huge vapour chambers for example.

Let's be realistic here, okay. Sure vapor chamber cooling are great inside the tiny confines of a notebook case. But vapor chambers still can't complete with full size heat pipes in a decent mid or full tower PC case. And for sure, any decent water cooler in a PC is more efficient than even the best vapor chamber cooling solution.
Sure, there are decent notebooks out there that game well. But even the best notebooks that are marketed as "gaming notebooks" are still compromises compared to gaming PCs. They still have heat control issues. They tend to be much thicker, bulkier, heavier (thus less mobile). They have a tiny display, cramped keyboard and no mouse. Of course, you can connect an external monitor, full-sized keyboard and mouse, but then you lose all mobility. And you still have the heat control issues.
I get it. Gaming notebook users love their gaming notebooks. And they are marvels in technology. But they are still notebooks in tiny notebook cases. The Laws of Physics apply. Notebook cases cannot support the same cooling capabilities in them that PC cases can. So notebook makers have to incorporate compromises and mitigation technologies to prevent thermal damage due to the excessive heat that will be generated but can't be expelled fast enough from those notebook cases.
