Aluminum Alloy Case Box with Dual Fan Heat Dissipation Accessory for Raspberry Pi 4 B+

Feature: 1. Aluminum alloy shell, oxidation sandblasting process, high hardness, strong pressure resistance, metallic luster, not easy to rust. 2. Ultra thin design, easy to install, built in thermal column, fast heat dissipation, all ports and slots of the shell are suitable for Raspberry Pi 4 B+. 3. Heat generated by CPU is transferred to the aluminum alloy shell through the heat conduction column, dual fans further enhance heat dissipation effect of aluminum alloy itself. 4. Easy to produce a dense and firm protective film on the surface, which protects the substrate from corrosion, is lightweight and durable, and has strong wear resistance. 5. The opening design can ensure that our shell will not affect the wifi signal, and it can be equipped with a cooling fan, and stable performance.
