Hi,
Thanks for all the encouraging comments :-). Yes Kent, first approach was fans in parallel, as they are simple two wires ones, I suspect they won't have a voltage range very large. I fear in series, each one receiving 2,5V, they won't move at all...
Another solution to have them both in parallel, but in serie with a small resistor to lower just a bit the 5v, having it high enough to have them running, but just enough, no more...
I'll have to test this on breadboard first, as the are rated 5v 0.15A, hence they should have each 33,3ohms, so if I want to drop voltage accross them put in parallel, I'll need something like a 1,5ohm resistor 0.2W... Currently I don't have that but I'll try and find it.
Regards,
Greg
