The laptop fans are also targeting a set (maximum) temperature. If you provide external cooling, the internal fans will simply work less and the temperature will remain stable. So check the RPM of the internal fans too.

Another factor is the CPU behaviour. The CPU involved in the article is intel, but IIRC for AMD Zen4 (at least for desktop) they made them boost up to a relatively high but well within spec temperature, rather than leaving performance on the table that only tweakers will see. The better your cooling capability the more you'll get but it caused a few people to freak out a little. Aspects like that are why I reserve the noisy part of my fan curve for when temperatures are going beyond normal.
