The entire case acts as a heat spreader — no fans needed. Keeps the Pi running cool under sustained load, completely silently. Features Full aluminium construction — the whole case is a passive heatsink Completely silent — no fans, no moving parts Thermal pads included for direct contact between the CPU/RAM and the case Significantly reduces CPU throttling under heavy load compared to bare Pi or plastic cases All ports accessible: USB, Ethernet, HDMI, power, audio Compact, professional appearance Why a Metal Heatsink Case? The Raspberry Pi 4 runs hot under load — hot enough to throttle the CPU and reduce performance. A metal heatsink case eliminates this by conducting heat away from the processor and radiating it across the entire case surface. Perfect for 24/7 server applications where you need maximum performance and zero noise (Pi-hole, Home Assistant, NAS, etc.). Questions? Message us anytime.
