Also you need to consider that cheaper coolers using direct contact heatpipies such as the Brocken are potentially sub optimal for the off centre chiplet design of Ryzen 3000s. The squished copper heatpipes are going to be eliptical / oval so won't be making full contact with each other to transfer heat accross all of the pipes unlike the more expensive coolers that use a full copper (nickel coated) heat plate for this purpose..........So should be easy to see why there could be some less than optimal cooling performances with chiplet design Zen2....
And ones that use direct contact heatpipes.And if wanting the absolutely best cooling might want to to avoid more convex base coolers.
