Analyzing Threadripper Thermals: Big Base Cooling Wins

See the original posting on Anandtech

AMD’s Threadripper processors step quite far outside typical CPU designs in several ways, one of which is their relatively massive physical size. The CPU’s surface area is much greater than that of all consumer CPUs before them, including Intel’s LGA 20xx sockets. This sizable design choice is not because AMD couldn’t squeeze the CPU dies physically closer, but because Threadripper’s size is the minimum size that their engineers calculated to be effective for both the mechanical strength of the package and for sufficient heat dissipation. When Threadripper was announced, nearly all cooler manufacturers rushed to provide adapters for their products to be mounted on Threadripper processors. AMD themselves include an adapter for Asetek-based liquid coolers inside the package of the Threadripper processors. User experiences with such adapters, including our own, were less that ideal. So today we’re going to take a look at why AMD’s thermal requirements are so exaggerated and showcase why adapters are not effective.
