The Passive Cooling Heatsink Case for the Raspberry Pi 4 is our own design manufactured right here in our warehouse! Designed to keep your Raspberry Pi 4 cool with zero noise, the case features a HUGE 23mm x 18mm aluminium heatsink that passes through the top glass-look lid of the case! We've included our usual signature 'hex' ventilation to further aid cooling, and included a set of rubber feet for keeping the case steady on your desk. The heatsink has a special aluminium foil adhesive ensuring a solid connection with the Raspberry Pi's CPU. In our tests, this case and heatsink combo dropped temperatures by ~10 degrees when using a Raspberry Pi stress test scenario (your mileage may vary depending on ambient temperature, software usage and other factors). It's the Hot Rod of Raspberry Pi cases! Important Notes * Simple assembly required - please see the assembly guide. * Shims and HATs are not compatible with this case (that big ol' heatsink gets in the way!)
