i do have a 3rd wire for the speed control on my fans, but i don't know what circuit I am supposed to build.What current do i use to supply that 3rd wire? what potentiometer should i use with the LM317T?
[SOLVED] what's the electric part i need?
I'm trying to put 2 x 12 volts fans in my pc. I found the right wires on the psu,
so i can plug them in and they work great. However, i need to be able to control the speed they're going at, because they're too noisy. I bought a couple Potentiometers...
