Im not reading any voltage across any of the fan ports even if I turn "on" a fake fan I've created using a pin like PD13.

well it is a controller_fan, it should be on when the motors turn on, Its a simple 2 pin fan it doesnt have PWM really, its just a voltage thats on or off

well theres a provision in ratos for a controller fan, which should turn on whenever the motors are engaged. I see when I home it goes to 100% for the controller fan but the fan itself isn't spinning, and no voltage is being measured across the pins.
