Raspberry Pi 4 Noctua fan 40mm cover case

thingiverse

This is a compact case/cover for Raspberry pi 4 that prioritizes minimalism while accommodating active cooling through a small fan. The goal was to craft the smallest cover possible, one that allows for the installation of a tiny fan without sacrificing functionality. The fan has been securely fastened to the 3.3V port, ensuring it runs at a reduced speed and produces almost imperceptible noise. This thoughtful design choice maintains an exceptionally quiet operation while still providing adequate cooling. Notably, the CPU temperature consistently remained below 60°C during extensive testing with cpuburn, demonstrating the effectiveness of this cooling system. The use of M3 screws throughout ensures a secure and stable assembly process.
