The Raspberry Pi 3 tends to overheat when pushed to its limits. When the processor’s internal temperature approaches 85 degrees Celsius, it protects itself by clocking down or shutting down completely, and the performance of our AI models takes a hit.
These infra-red images show a Pi running idle (left) and after a few minutes of running a compute-intensive AI model (right). Notice that the main processor heats up much more than any of the other components on the board. Some cooling kits for the Raspberry Pi include heatsinks for the other components, but these infra-red images suggest that we should really focus on cooling the processor. In this tutorial, we will build a simple and effective active cooling solution for the Raspberry Pi 3.
