LED Mod
after some research, I found blue LEDs run at 3.0-3.6 volts and if LEDs are run in series they distribute the voltage equally thoughout all LEDs.
so (4) LEDs per fan 12/4=3 Volts per LED
since my fans are all severly undervolted (5V) the LEDs do not light up.
To fix this I wired the LED group seperately to the 12V line and the lights are back on.
