Wondering if anyone else has issues with getting the part cooling fan to work. I have not been able to get mine to turn on at all. Ive checked with a volt meter and there is no ground signal out from the plug. I have a full 24v, but the PWM ground signal is not seeming to function. This is my replacment AIO II that took me 2 months to get due to the shipping slowdown, and it also arrived without power plugs and no control knob. (i would like one trasaction with FYSETC to go without issues just once...)
