This is the Flagship Vilros Aluminum Alloy Case for Pi 5. It is a 2-part case designed to have the top part contact the main chip and pull the heat away from the board. For situations of heavy use when the passive cooling is not adequate, the case also features a 10,00 max RPM Built-in PWM fan with a fan connector that connects directly to the fan port on the board and will automatically power on/off as needed as well as increase/decrease RPM based on the board temp. In addition to great venting the cases, open slots on all sides offer a lot of flexibility for those looking to use many camera/display cables as well as an RTC battery. The case also has an option for use in an open configuration without the top part for GPIO use as well as combability with most HATs. When used without the top the case is compatible with the official active cooler
