Hey Toms Hardware
I'm in need of help, I want to add in my own LEDs to my fan like this -
My fan has its own holes all ready for me to do it but I need help with which Resistor I need and which Potentiometers I need as I'm wanting to add some RGB LEDs into my Fan, which means I can adjust to any colour I wish.
They share the same cathode but each have separate anodes.
The Red section has a max of 30mA and a normal forward voltage of 1.9V
The Blue section has a max of 30mA and a normal forward voltage of 3.2V
The Green section has a max of 30mA and a normal forward voltage of 3.2V
I would like to know what Resistor I would need for each of these, bearing in mind I am using 4 LEDs connecting to one Molex connector. Also I would like to know what Potentiometer I would need to be able to dim the LED from 0 to 100% brightness.
I am thinking of going Power > Resistor > Potentiometer > 4 LEDs in Parallel which would work for me for each the red, blue and green sections, although I was then wondering if there was a way to be able to add in LEDs running off the same power supply and being controlled by the same potentiometer (I am going to have three, to control red blue and green sections).
Help asap would be helpful, I will be online lots to check for updates from people.
