Single Fan Heat Sink CNC Protective Cover for Raspberry Pi 4 Aluminum Alloy Case RadiatorBlue

Feature: 1. The external slot of the aluminum alloy shell does not affect the transmission of wifi for bluetooth signals. 2. This heat sink with built‑in heat column, the shell can be equipped with a cooling fan to make heat dissipation more effective. 3. The surface is easy to produce a dense and strong protective film to protect the substrate from corrosion, light and durable, strong wear resistance and not easy to embroider. 4. The aluminum alloy material is oxidized and sandblasted, which is glossy and not convex, high hardness, pressure resistance, and strong metal luster, not easy to rust, and aluminum alloy material is more conducive to heat dissipation. 5. This heat sink in aluminum alloy trough design, greatly increase the heat dissipation area, cool to a safe temp to avoid overheating and throttling, improving the performance of your computer Specification: Item Type: Single Fan Heat Sink.Material: Aluminum alloy Applicable Models: Applicable to for Raspberry Pi 4 Package List: 1 X Upper Shell1 X Lower Shell1 X Fan1 X Screwdriver8 X Screws3 X Heat Sink
