Replacing the flashing red E on the EVGA E760 motherboard (might be used on others)

post #1 of 4
Thread Starter 
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)
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 motherboard out of your case or wherever and remove the 6 screws on the back holding the NB heat sink 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 heat sink 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

different color LED's can have different resistance ratings. Red LED's have the highest ohm resistance of the LED's. using a lower rated LED could possibly cause the board to fry. i wouldnt do this unless you were sure that the LED's you were replacing matched the LED's that come with the board. youd need to test the voltage going through the LED's aswell as the resistance.

I'm pretty sure i'm good to go but if you could maybe give me a hint on how to check the resistance.

alright well I had to purchase the LEDs from somewhere else as shipping took too long but I got everything up and running with no issues. First post updated
