Product description: All-In-One - cooling fan with heatsink - aluminum - with PWM regulation + adapter for Raspberry Pi 4B - Waveshare 22931
All-In-One from Waveshare is a 2-in-1 product that combines a heat sink and a fan . The element is made of high-quality aluminum , which allows for effective heat dissipation from the Raspberry Pi 4B. The fan has adjustable rotational speed (using PWM ), thanks to which the user can set the speed of rotation of the blades according to individual needs. The maximum number of revolutions is approximately 5500 ± 10% rpm . The set also includes a special GPIO adapter that allows the installation of additional overlays.
Product compatible with Raspberry Pi 4B!
Also check the manufacturer 's user guide . There you will find, among others, instructions for assembling elements and sample program code.
All-In-One - cooling fan with heatsink - aluminum - with PWM regulation + adapter. Raspberry Pi 4B must be purchased separately.
Connecting the fan with the Raspberry Pi.
Special features
- The 2in1 All-In-One version allows for more efficient heat dissipation
- Ultra-quiet fan and lightweight heatsink
- Design adapted to the Raspberry Pi 4B in terms of the spacing of mounting holes and GPIO pins
- An additional adapter that allows you to extend the Raspberry Pi 4B with additional overlays
- Possibility to adjust the rotational speed using PWM
- Compatible with official system configuration

Pin description
The fan has 3 leads in different colors that should be connected to the Raspberry Pi in accordance with the following:
- Blue wire - PWM signal - TXD / D12 / D18 pins *
- Red wire - 5 V - supply voltage
- Black wire - GND - system ground
*When using a fan adapter, the default PWM pin is D12 (GPIO12).
