ACTIVE COOLING UNIT FOR RASPBERRY PI 5

1. General Information

Dear customer, thank you for choosing our product. This guide will show you what you need to bear in mind during commissioning and use. Should you encounter any unexpected problems during use, please do not hesitate to contact us.

2. Assembly

First, insert the fan unit into the heat sink and mount it using the four screws provided.

Now, completely remove the protective film from the thermal pads and place them on your Raspberry Pi.

⚠️ ATTENTION! There is a protective film on both the front and back of the heat conducting pads. Both must be removed before fitting.

Now, place the heat sink on your Raspberry Pi.

The fan is now ready for use. A separate installation and/or configuration is not required. ✔️

3. Fan Control ⚙️

Normally, the fan is automatically controlled by your Raspberry Pi depending on the CPU temperature.

However, you can also use the following commands to control the fan:

• Disable the fan: pinctrl FAN_PWM op dh ❌
• Run the fan at full speed: pinctrl FAN_PWM op dl
• Automatic control of the fan: pinctrl FAN_PWM a0

To change the parameters for automatic fan control, enter the following command:

sudo nano /boot/firmware/config.txt

Add the following three lines to the end of the file:

dtparam=fan_temp0=47000
dtparam=fan_temp0_hyst=6000
dtparam=fan_temp0_speed=165

You can adapt the individual parameters to your application:

• The first line specifies the temperature threshold in milliCelsius.
• The second line specifies the fan hysteresis in milliCelsius.
• The third line specifies the fan speed (PWM setting) (0-255).

After you have adjusted the values, you can save the file with CTRL+O and Enter and close it with CTRL+X.

The settings are only applied after the next restart. To do this, enter the following command:

sudo reboot
