I believe the RPiOS default setting is GPIO-14, which is Pin-8 on the 2x20 header, and that would be correct for the picture on the box. However, that pin is also used for the GPIO serial port (which I have enabled), so I put my fan on GPIO-18.I was using the wrong pin due to this guide from the cooler box.
...
Now I am using GPIO 18.
You can use whatever GPIO you want, you just have to set the correct GPIO# in the configuration.
