Hey guys,
Just two questions. I found an old pc fan I can power with my old TT scale train power supply. Housing and everything else is done as well.
Now I have to glue the magnet on the fan and buy that small doodad that spins around.
What is the direction of the magnet's polarities supposed to be? Is it horizontal (90 deg to rotational axis of the fan) or is it vertical (parallel to the rotational axis).
I'd say the first, but I'm not sure.
Won't a strong earth magnet damage the fan or lower it's efficiency?
Thanks!
