1. Place silicon thermal pad (included in the pack) on the CPU of your Raspberry Pi.
2. Make sure that the header of the Argon Mini Fan HAT is aligned with pins 1 to 12 of the Raspberry Pi.
3. Check if the heat sink of the Mini Fan is in contact with the Raspberry Pi CPU, to ensure the heatsink functions effectively.
Set mode of the Argon Mini Fan:
ON: Mini Fan will always turn ON when the Raspberry Pi is powered, no script installation is needed
OFF: Turns OFF the Mini Fan
PWM: Sets the Mini Fan into a pulse width Modulation controllable mode, will need to install script in the Operating System
Setting the PWM settings:
In Raspberry Pi OS (a.k.a: Raspbian), open the Terminal App
Go to the root directory and open
/boot/config.txt file
Open and edit the "config.txt" file by typing:
sudo nano config.txt
Add the line:
dtoverlay=gpio-fan,gpiopin=18,temp-55000
Press Ctrl+X to save changes and exit
Note: This setting will start the Mini Fan at a CPU temperature of 55 degrees Celcius (temp=55000). You may set your own desired initiation temperature as you wish.
Features:
Uses 12 of the 40 GPIO pins on the Raspberry Pi
Fully controllable with its switch
Can turn on at any assigned Temperature when set to PWM Controllable
Has a heatsink for additional cooling
