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.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
