I think we are mising something here with the following statement:
"Keeping in mind that AMD has recommended to use 360-mm closed-loops liquid coolers with is Ryzen 5000-series processors and Intel's upcoming Rocket Lake-S CPUs might likely be rather hot too, mainstream platforms for enthusiasts are going to need advanced air coolers like ID Cooling's SE-70 that is rated for up to 280 W. "
First of all AMD has announced the Ryzen 5000 series should slot around the TDP (if not the same or below) of the 3000 series. In fact many people till this day have failed to realize that for example, the Ryzen 5600X is a 65Watts TDP cpu, when the old 3600X is a 95Watts part.
We all know TDP does not tell even half of the story, but I realy don't believe you will need a 360mm closed loop liquid cooler or a 280watts twin tower one to cool down every single Ryzen 5000 series, and specially not at stock settings.
Of course once you hit the OC land thats a whole new story.
I can't not talk about Rocket Lake desktop chips cause they are still far away, but if I have to guess they will probably get as hotter as the 10th gen series.
