I would like to reduce the 12V+ source voltage going into computer fans
with potentiometers place between the 12V+ and the fan. I am unsure
what Ohm rating potentiometer I need to get could someone please help.
All I remember from physics class was that V=IR formula. So I guess
that means R=V/I = 12/I The fan has a label that says 0.8A on it. So
I guess that means R=12/0.8 = 15 Ohms max ? Kinda small? I only have
on hand a potentiometer that say 15K ohm.
Could someone please share me their experience using pots to
dynamically reduce a 12V source voltage.
