Sony has officially posted a teardown of the PlayStation 5 yesterday revealing the innards of the console. Highlights of the teardown include the ability for users to add an M.2 NVMe SSD, the mainboard itself, and the cooling mechanism. The PS5 is using a 120 mm double-sided fan to drive hot air away from the massive heatsink, which interfaces with the AMD Zen 2 SoC via a liquid metal thermal interface material.
