the google language model said that the fan control board i have already has diodes to make it behave in a more power stable manner. it says the relays are likely missing these diodes. i've also successfully spun the fan by carefully increasing PWM to a pin controlling it, without causing any issues. so with just servos and the fan, especially if the servos are not adjust while the fan is running, it may be quite stable, so long as (a) power to the fan is ramped up slowly and (b) the relays are disconnected
i don't really understand it well {and got [learning] inhibition around these oscilloscope-like things before beginning exploring them ...
