Why use a heatsink and a case, when you can use a heatsink case?! This sleek, anodised aluminium case for Raspberry Pi 4 will give you 10-15C of passive cooling under full CPU load. Pretty cool. This anodised aluminium heatsink case will protect your Raspberry Pi 4 and give you the best passive cooling we've seen in our extensive testing. It's great for situations where you want completely silent cooling, like home media centres. 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. The case gives you access to all of the ports, pins, and connectors. You can just about get away with using low-profile HATs and pHATs (those without bulky components on the underside, using one of our booster headers, but be extremely careful not to short any components on the metal top case!
