Pimoroni - Raspberry 4 Fan SHIM

Make your Raspberry Pi 4 seriously cool with Fan SHIM! This 30mm no-solder, controllable CPU fan with RGB LED and tactile switch will give your Raspberry Pi significantly better thermal performance It"s whisper-quiet too!Fan SHIM uses a friction-fit header, so it just slips onto your Pi"s pins and it"s ready to go, no soldering required! Note that, due to the height of the fan, if you want to use HATs or pHATs with Fan SHIM, then you"ll need to use a booster header

The fan can be controlled in software, so you can do crafty things like toggle it on when the CPU reaches a certain temperature. Use the LED as a handy visual indicator to show fan status, CPU load/temperature, whatever! The tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode.Features30mm 5V DC fan4,200 RPM0.05 m3/min air flow18.6 dB acoustic noise (whisper-quiet)Friction-fit headerNo soldering requiredRGB LED (APA102)Tactile switchBasic assembly requiredCompatible with Raspberry Pi 4 (and 3 B+, 3 A+)Python library and daemonPinoutKit containsFan SHIM PCB30mm 5V DC fan with JST connectorM2.5 nuts and boltsAssemblyAssembly is really easy, and will take less than two minutes.SoftwareOur Python library lets you control the fan (on/off), RGB LED, and switch

There"s a handful of examples to show you how to use each feature, and a script to install a daemon (a service that runs in the background) that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with a manual override via the tactile switch.Notes* When mounting or detaching the fan, or assembled Fan SHIM, do not push on the fan itself, as it is liable to break.* Be careful to mount your Fan SHIM on the correct pins on your Pi, with the Pi shut down and power disconnected. Shifting it left by one pin or down a full row of pins could cause damage to both the Fan SHIM and the Pi.
