If you’ve used the new Raspberry Pi 4, or read much about it, then you’ll know that it can run pretty hot under high CPU load. Let’s take a very quick look at it’s thermal performance, and how a couple of different cooling options perform, in particular our new Fan SHIM.
With each generation, the Raspberry Pi packs greater performance into a same-sized package, and the Raspberry Pi 4 is one of the most significant steps up so far. The Raspberry Pi 3 was known to run hot, but the Raspberry Pi 3 B+ dramatically improved thermal performance with a metal heat-spreader on the System-on-Chip (SoC), and much better thermal dissipation through the PCB. The Pi 4’s higher performance means that some of that heat creeps back.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
