The article also goes over the concept of using this tool to 'optimize' for battery life and overall product longevity. That said, this excites me as I already have used a similar tool on a ryzen 5 2500u series laptop with an upgraded cooler to effectively double its performance while staying WELL within thermal tolerances.
Some 'consumer' laptops share cooling component compatibility with 'gaming' units and 'consumer' models with dedicated graphics chips. These coolers are designed for much more thermal load. In my example I was able to put a Nitro 5's cooler into an Aspire laptop, additional fan and all (with some custom wiring and soldering.)
I do not know if there are any Renoir units with this capability, but it is not terribly uncommon to cut down on casing and component costs by sharing parts between varying configurations. I have also seen adventerous users of earlier APU laptops solder/thermal epoxy in additional heat exchangers and heat pipes.
So, I think this is a fantastic and powerful tool for modders and power users or merely those willing to sacrifice performance for battery life and a cooler lap(top).
