"Temperature-controlled fan" so how do you mean with "fans do not work"?

I etched the raspi 4 img onto it and the fans do not work, my raspi has overheated multiple times and none of the times the fans turn on. SO then I tried just a normal sd into one of them and the fan was spinning. I am looking where I can manually turn the fans on all the time.

I am not at them rn, usually I just ssh into them. But I know there raspi 4's I may have given the wrong image up top.

If you can find a schematic I could help you with circumventing the temp sensor.
