Overview:

• This is an armor aluminum alloy case with dual cooling fan designed for the Raspberry Pi 4 Computer Model B. It is a great raspberry pi 4 passive cooling case to help raspberry pi 4 board cooling down. Also a Raspberry Pi 4 Heatsink Case (Raspberry Pi 4 Case) for good heat dissaption.
• There are two case versions for you to choose, Case A with dual fan, Case B without fan (black color and grey color for your choice).
• Note: If you think the blue Thermal Tape is not good enough for heat dissaption, you can replce it with thin 0.5mm cooper heatsink match with silicone grease (recommend Shin-Etsu Shin-tsu X-23-7921-5) for better heat dissaption.
