I've seen other gimbals/cameras for sale with a fan here, my brothers P3A has a fan here but mine does not, is it possible it was lost when I crashed recently, wasn't a bad one just the large ribbon cable and the anti vibration board were broken, theres no witness marks from any screw threads in any of the 4 mountings (if that's what they are), and what's it connected to, I have no loose wires visible, just curious
