3. Setup & Installation
Follow these steps to install your cooling fan:
3.1. Connecting the Fan to Raspberry Pi GPIO Pins
The fan can be connected to either the 5V or 3.3V GPIO pins on your Raspberry Pi. The 5V connection provides maximum cooling but may result in higher noise levels. The 3.3V connection offers quieter operation with slightly reduced cooling performance.
Image: Schematic showing the GPIO pin locations for connecting the fan to either 5V (red circles) or 3.3V (red circles) power on the Raspberry Pi. Note indicates 5V connection may be noisier but reduces heat better.
3.1.1. 5V Connection Method
Connect the red wire of the fan to the 5V pin and the black wire to a Ground (GND) pin on your Raspberry Pi's GPIO header. Refer to the diagram for exact pin locations.

3.1.2. 3.3V Connection Method
For quieter operation, connect the red wire of the fan to the 3.3V pin and the black wire to a Ground (GND) pin on your Raspberry Pi's GPIO header. Refer to the diagram for exact pin locations.

3.2. Mounting the Fan
Use the provided screws and nuts to securely mount the fan to your Raspberry Pi or compatible enclosure. Ensure the fan is positioned to direct airflow over the CPU for optimal cooling.
4. Operation
Once installed and connected, the fan will begin operating as soon as your Raspberry Pi is powered on. No additional software or configuration is typically required for basic operation.
4.1. Noise Levels
The fan operates at a low noise level of approximately 25 decibels. Connecting to the 3.3V GPIO pins will result in quieter operation compared to the 5V connection, which provides maximum airflow and cooling.
5. Maintenance
To ensure longevity and optimal performance of your cooling fan, consider the following maintenance tips:
- Regular Cleaning: Periodically inspect the fan blades and surrounding area for dust accumulation. Use a soft brush or compressed air to gently remove any dust.
- Inspection: Check the fan for any signs of damage or loose connections. Ensure the mounting screws are secure.
6. Troubleshooting
6.1. Fan Not Spinning
- Check Connections: Ensure the red and black wires are securely connected to the correct GPIO pins (5V or 3.3V and GND).
- Power Supply: Verify that your Raspberry Pi is receiving adequate power.
- Obstructions: Check for any physical obstructions preventing the fan blades from spinning.
6.2. Excessive Noise
- 3.3V Connection: If connected to 5V, try switching to the 3.3V GPIO pins for reduced noise.
- Mounting: Ensure the fan is securely mounted and not vibrating against any surfaces. Loose screws can cause noise.
- Dust: Clean any dust buildup on the fan blades.
6.3. Insufficient Cooling
- 5V Connection: Ensure the fan is connected to the 5V GPIO pins for maximum cooling performance.
- Airflow Obstruction: Check that there are no obstructions blocking the fan's airflow to and from the Raspberry Pi's CPU.
- Thermal Paste/Pads: If using a case, ensure proper thermal paste or pads are applied between the Raspberry Pi's CPU/RAM and any heatsinks or the case itself (if applicable).
