This guide will allow you to sync most individually addressable LED strip with motherboard RGB headers. Most RGB fans use individually addressable LEDs. I have only tested this with Corsair SP120 fans and WS2812 LED strip. However it should work just fine with other fans/LED strip, as long as you know the control protocol used by the LEDs in the fan. I know the HD120 fans are also compatible with this, as they use WS2812 LEDs.
Before I start, I should say that this worked for me, it won't necessarily work for you and its your responsibility if you break stuff. If you don't own a multi meter, this project is probably not for you, as it requires a fair degree of electronics understanding, and a multimeter will be invaluable to make sure you have the circuit which steps down the voltage from the Aura header working correctly. You WILL break your micro controller if this circuit is not working correctly.
Be warned, I have only tested this using Asus Aura RGB headers. Trying to use the exact same circuit with other RGB headers, without first verifying they output the same voltages as Aura headers, or adpting the circuit as required, you have a very real possibility of breaking something. If your lucky it will be your circuit/microcontroller. If not, at the very least your RGB header will be broken, possibly the entire Aura circuitry and maybe something more serious.
