Hello! I was just wondering if there was a downloadable script for the Raspberry Pi 4 Case Fan (a script like the one for the Argon One fan). I know how to use it with Raspberry Pi OS but I would like to use some other Linux distros. Thank you!

Hi Willem,

All you’d have to do would be to turn on and off the control pin on the Pi that the fan plugs into.

Someone made a simple script for this, you’ll just have to double check that running the gpio and vcgencmd command will work in your OS:

gpio -g mode 3 out
temp=$(vcgencmd measure_temp | egrep -o '[0-9]*\.[0-9]*')
echo $temp #use BCM pin 3, as pin 2 is used for PSU control
echo $temp0

if [ $temp0 -gt $ontemp ] 
	echo greater than $ontemp fan on
	gpio -g write 3 1
	echo less than or equal to  $ontemp fan off
	gpio -g write 3 0

All the best with your cool Pi!
