Kkeep your Raspberry Pi 4 cool with Fan SHIM! 30mm software controllable CPU fan with RGB LED and tactile switch will give your Raspberry Pi much better thermal performance without a lot of noise.
Fan SHIM uses a friction-fit header, so it fits onto your Raspberry Pi's pins. Because of the height of the fan, if you want to use HATs or pHATs with Fan SHIM, you will need to use a booster header.
This fan can be controlled with software, so you can do neat things like toggle on when the CPU gets to predetermined temperature.
Visual Status Indication with LED, CPU load/temperature.
The tactile switch can be programmed as well so you can use it to toggle the fan on or off, or for switching between temperature-triggered or manual mode.

Kit contains
Fan SHIM PCB
30mm 5V DC fan with JST connector
M2.5 nuts and bolts
Assembly
With the component side of the PCB facing upwards, push the two M2.5 bolts through the holes from below, then screw on the first pair of nuts to secure them and act as spacers.
Push the fan's mounting holes down onto the bolts, with the cable side of the fan downwards (as pictured) and the text on the fan upwards. Attach with another two nuts.
Push the fan's JST connector into the socket on Fan SHIM.
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.
Not heatsink-compatible!
Because Fan SHIM uses pin BCM18 to control the fan, and this pin is also used by I2S audio devices, you won't be able to use I2S DACs like pHAT DAC, pHAT BEAT, and the IQAudio boards at the same time as Fan SHIM
