I have installed 2 EK waterblocks on my FTW3 sli's but no backplate light for me, I am 100% positive that i connected them correctly but in precision oc the option is blocked out now, any help?

HMM!! maybe, i am not sure i have tried to uninstall software drivers etc... but still nothing not sure hopefully someone can find out kinda doesn't make sense that they would support the factory back plate but led will not work.

Lol yes that is the problem the 2 options are grayed out for me i understand the thermal led being grayed out, but not understanding the back plate led

Finally got around to it.

how did you go about removing the led logo from cooler is it one piece?

Really don't want to take cards apart sime they are already in my loop just can't figure out why the backplate led's are not working like you mentioned before i wonder if they are part of a chain that needs all connectors linked for all led's to function. Thank you bye the way

Right!! Hmm if I can't figure it out looks like I'll just go with the ek nickel backplate, but Jacob said new PXOC will be out tomorrow with new skin so maybe it will fix the issue

Same issue for me :/

Hi guys.
I plan to buy the 1080 Ti FTW3 and put a water block on it. I just wonder if it's better to buy a Hybrid version and then replace the block.
Are there any differences in BIOS of these versions?
Is it possible to use the BIOS for Hybrid in FTW3?

Go with the Hydrocopper from the start.  It will save you money and time.  

I agree, Graphite8five.

I agree, Graphite8five.

Yeah the RGB badge on the FTW3 is sexy, I'm just bummed about the fan hum, if fan noise was consistent throughout the rpm range I would be super happy.
 
On air I max 60-62C and average 50-55C which is really pretty good for most of my games at 80-90 fps 3440x1440. I'll admit I'm not maxing my games out fully and some settings might bring the temperature up a bit but framerate's tend to suffer also. It appears that I cannot get temps better than this on air. I'm not sure how this compares to the Hybrid and custom loop temps.

I'm in the process of installing my EK waterblock. Judging from the things I'm reading on different threads in this forum, the backplate LED issue when a waterblock is installed is not yet fixed (again, shame on you EVGA for not fixing multiple issues with this freakin' expensive card!). I forgot to set the color to my liking before taking the card apart so I'm assuming that red will be the color of the backplate LED when I fire it up. It doesn't matter much because my GPU will be mounted vertically anyway but I still want to know are you able to turn off the LED completely with Precision OCX? Or should I just leave the cable disconnected? Or just do what the other person here did and connect the G and GND pins to the header only? Green is what I want, btw.
 
EDIT: I don't think Bombenfreak's idea will work in my case because the card has the LED set to Red in the first place. So I'm assuming the PCB header will not give 3V to either G or B pins.

AHowes
Actually the backplate led will not work at all with the ek block installed.

No lights!

I have some rgb lights in the case and they make the led panels on the card glow hehe. :/

Wait, I thought it will work but the lights can't be changed from what they are BEFORE installing the waterblock? There was a guy that claimed this.
 
And how did Bombeenfreak's technique work?

AHowes
No lights.. darkness. After removing the evga cooler and installing the ek wb.

 
Right but why do other people observe otherwise?
 
EDIT: Just finished mounting my EK waterblock to my EVGA GTX 1080Ti FTW3 and tested it right away (without coolant) on an old computer. Here's proof for you :)
 

 
So Bombenfreak's suggestion would work. The LED defaults to white when the main RGB LED from the stock fan assembly is disconnected. I'm not sure how the other guy claimed that you just need to set the color of your choosing before installing the waterblock and that will be the color that will show when you have the waterblock installed.
