This mod is to take that Red E flashing on the motherboard and to change it to any other color LED.
Example:
Originally came from here but I thought a guide would be nice ;) 

 
WARNING: MOST LIKELY YOU WILL VOID YOUR WARRANTY, AND I TAKE NO RESPONSIBILITY IF FOR SOME REASON YOU MAKE A MISTAKE DOING THIS MODIFICATION. MODIFY AT YOUR OWN RISK!
 
 
Things you will need to complete this mod:
Glue gun
Soldering Iron
Heat shrink (very small, I believe I used 1/8th inch)
Two 3mm LEDs color of your choice
Philips head screwdriver (to get NB heatsink off)
Craftsman 00 X 1-1/2 Philips head screwdriver
thermal paste to reapply once finished - Recommend shin etsu
 
First step is to take your mobo out of your case or wherever and remove the 6 screws on the back holding the NB heatsink on.

after you will need to remove two screws, for this i had to use a specific screwdriver to get them out (and a lot of pressure).


carefully remove the top of the heatsink and then push / pull the wire through the heatsink hole. Once You've done that you should see this

remove the glue and you should come out with this

Cut the old LEDs off. Try and cut as high up as you can so you have more wire to work with:

If need be cut some of the LED wire off, once that is done set the LED wire at a 90º

Soldier and use heatshrink to connect the new LEDs (sorry I did a crappy job so I don't have many pictures of this)

Use the glue gun to put the LEDs back in place

Reattach the top of the NB heatsink. Also don't forget to put thermal grease back on where you took it off

And here is my finished product

 

Sweet! What color you going?

Awesome! I was actually looking around to see if anyone had done a similar mod like this back when I got my P55 FTW. I would love to have that LED blink white instead to match my blue LED fans.

I would be happy with mine just staying solid instead of fading in and out.

me too but that goes a little past my expertise at this time.

nice one man, Blue would look nice if using EVGA GTX 580's they have blue decals also

Couldn't you just use a 3-pin fan connector instead, since you're already modding the wiring, and plug the LED into a nearby motherboard fan header for constant +12v lumination?

It might work but If I am correct too much voltage through those LEDs will blow the LEDs really quick

 
Yep... that's a green E on my 760

make sure to post a pic
 

Here is the finished product. The person I originally ordered from didn't ship them out until today so I might go ahead and switch these LEDs out again at a later date as the ones coming in should be brighter.

I have a nikon coolpix p100, didn't use flash and shut off the light and used shutter priority on the camera. I just played around until I got a good picture

Gret job:)

Unfortunately one of the LEDs I changed has an occasional fast flicker that suddenly started.
 
I took the cooler cover off and connected it right to a 3V battery and there is no flicker.
 
Not sure what to do. The wiring is intact and nothing seems to be touching or grounding. I have everything heatshrunk just as stock.
 
I've re-installed the stock cover with the red LEDs for now and its not flickering at all.
 
LEDs going bad?
 
I'm curious to know the voltage coming from those pins on the motherboard.

Thanks for this thread. Just changed out the red E on my daughters P55 FTW motherboard to match the blue fans in her case.
 

 

Nice simple mod
Just wish my X58 FTW3 had the E....
