Why use a heatsink and a case, when you can use a heatsink case?! This red, anodised aluminium case for the Raspberry Pi 4 will give you 10-15°C of passive cooling under a full CPU load. This case is great for situations where you want completely silent cooling, like home media centers.
It comes with a thermal pad to provide thermal contact between the CPU and top case, and a handy Allen Key and set of hex bolts to attach the case together.
