The Raspberry Pi 4 heats up during high processor load and internally throttles the CPU speed down to prevent damage. This causes your programs to run slower during high CPU load. To prevent this we have to extract the heat from the processor and transfer it to the surrounding environment. This case does exactly this and keeps your processor running cool and fast.
This rigid Aluminum case is capable of providing a better cooling solution for your Raspberry Pi 4B. It does that by having a dual-fan system and a heat sink.
The thermal pads align with the heat sink perfectly to achieve better heat dissipation. The thermal pads cover all the heat-generating components except the wireless chip. The I/O ports and slots such as USB-C power port, micro-HDMI ports, audio port, USB ports, SD card slot, camera port, GPIO pins, display slot, and others are easily accessible when using this case. This case has an acrylic window on the side that helps in improving WiFi/Bluetooth performance and makes status lights visible. It also provides easy Micro-SD card access and camera cable passthrough
