Upright Raspberry Pi 4 with Passive Al Heat Sink Case

thingiverse

An upright fan case for the Raspberry Pi 4 with a passive heat sink (https://www.adafruit.com/product/4341). This case holds a Noctua 40x40x10mm 5V fan (or equivalent) to keep things cool. There's a duct to route the wires to the Pi GPIO pins to connect up. I’m only using +5 and Gnd but anyone wanting to do PWM control or RPM monitoring should keep the GPIO voltage limits in mind. There's a knockout if you want to use the monitor connector but knocking it out will let forced air shortcut out. As cool as these are running with this fan, that may not be an issue. The POE port has a cutout but the camera connector still is blocked like my other scarab version that clamps on. This one obviously doesn't clamp and it protects the heat sink and Pi much better. The Pi with heat sink and the fan drop in and the lid holds everything in place. On my printer it's a tightish friction fit and holds nicely. The passive heat sink for the Pi 4 with the Noctua fan is a nice combination.
