Got two of those babies in sli in my system
EVGA GeForce GTX 1080 Ti SC GAMING Black Edition
11G-P4-6393-KR
 
When SLI started to CTD games I started diagnostics and found out that secondary gpu was bad - crashing in every game, every benchmark after 1-2 minutes. Did test on 2 different PC's with fresh Windows and several driver versions so I am sure that this is the card faulty. But doing that I found some oily stuff that comes from inside the card, somewhere under backplate - probably where the GPU core is and I freaked out! Both cards have this problem! I don't have any liquid cooling systems in my pc. 
Primary card still working:

Secondary I am about to send to RMA but now decided not to because I will use distributors RMA where warranty will be denied because of liquid. You can see this oily stuff under the ribs. 

 
What is this? Some type of thermal pad breaking down? Will this be covered in warranty? Can i disassemble working card to clean this stuff and replace anything that causing this "bleed"? Can I get some approval from EVGA that such card can be replaced in warranty so I can avoid misunderstandings with my distributor or better to send this card directly to EVGA? I did contact EVGA support 5 days ago about general questions about support, but no answer yet.

    The oil is coming from the thermal pads under the backplate. It's harmless. The oil won't void your evga warranty. Yes, you can take the card apart to clean up the oil & replace the old pads with new pads if you want. It would be best to send the card to evga if you need to rma.

    When I took mine apart and when I got the SC2 Hybrid kit, I noticed that the included thermal pads were a bit weird even for stock ones in that they used a very sticky adhesive on both sides. Even without running the card this stuff gets left all over anything it touches for any amount of time - so all over the PCB, all over the backplate, fans, VRAM, VRMs, yeah. I could see how a bad few pads or getting too hot too quickly might cause this - there's a 1.5mm thick pad right under that EVGA logo.
     
    They're super cheap and really bad. I read somewhere they're something like 1W/m.K conductivity, which is around the lowest you can get but it's completely normal to get that as stock on everything. What makes them super cheap and really bad is the adhesive. If you compare them to the Fujipoly ones you get with a Bitspower block, or the EKWB ones, which are only adhesive on one side and use a tacky adhesive rather than the liquidy one you get with these cards, the difference is amazing. Even the ones you get on Gigabyte cards are far better - same green 1W/m.k pads, different adhesive.
     
    I saw these and was pretty disappointed. I'm not an electrical engineer, but from everything I've seen over the years and just common sense, the pads that go in these should be single sided tacky and the tacky side needs to be placed onto the backplate and heatsink - not onto the PCB. Again, not an electrical engineer, but first port of call was to order some halfway decent ones to replace them.

    Sad.. glad I'll be putting a ek water block on my ftw3 elite card to get away from these pads but crap.. there on the backplate as well and I'll still be using that!

    It's amazing that for years, this has been a cosmetic issue that has been complained about FREQUENTLY and is so easy to solve...yet here we are. I read these complaints on various internet tech sites almost always paired up with the OMGBBQ exploding GPU. EVGA, this is such an easy fix to get rid of negative publicity. So..what's the hold up?

    Gentlemen, what your seeing is the gap pad filler (silicone) seeping out of the thermal pad. It is not conductive or corrosive. The silicone is used to aid thermal conductivity and keep the component cool, also it prevents stress on the component by keeping the pad pliable. After years of use it will stop leaking and the ability to cool the component will not be as good as it was when it was new, and they should be replaced.
     
    A little bit of alcohol and a paper towel will clean it up.

    We (those commenting from experience) know this. We also know that other GPU makers do not suffer from the same "cosmetic" issue of  weeping pads. It's an easily solvable issue that would pay for itself in good will. I detest needing to do more work cleaning gunk off the GPU on a regular basis when a bit of air and a soft brush is all I should ever need.

    they really should use better pads, i usually just replace them with some good 7w/m.k pads when i change the TIM on the GPU, really helps the temps come down and stay down.

    The test that gamer nexus shows that the 1w/mk pads do a very good job at cooling the vrm and memory down substantially. Is there any tests to show the true performance of the higher rated pads?

    I honestly don’t care to see the, “tried them and see a difference” without substantiating tests. I definitely don’t care about manufacturer claims either. I like independent proof. I can’t really seem to find good websites that don’t spam my phone with irritating ads though, and all other pages are just forumnposts without proof or websites selling the pads.

    From looking at motherboard VRMs from boards with terrible heatsinks and fewer phases, I've seen a few pieces of anecdotal evidence that suggest they can make a major difference in that application. I pulled off the stock Gigabyte ones from my board and threw on some 6w/mk Fujipoly I had lying around. They are about 20c lower. Before during P95 small FFT they'd break 100c. After they don't break 80. I didn't measure delta but we're heading into summer. It is warmer than it has been and doing it now they're still levelling out way below 100c.
     
    But unlike the VRMs or SoC where the pads are the only method of heat transfer and where the VRMs are the only source of heat, and the heat is only removed in one direction, the GPU has three major sources of heat, different ways to remove it and removes it front and back.
     
    They're going make a difference? But it's sort of like the thermal paste difference. You might get a slightly better heat transfer between the 4w/mk stuff you get with a cooler and Gelid at 9w/mk but ultimately the thing that'll make the real difference is the cooler because the thermal pads only transfer heat to the cooler or the backplate, they don't dissipate heat. If the cooler is operating as well as it can then being able to transfer heat at a higher rate doesn't help. Those pads you get with the EKWB kits are 3w/mk and they do fine. Just for the price of the 1w/mk pads if you pay retail you may as well get the 3 or 6 w/mk.

    This is what I don't get about this. We've seen the reps respond to these threads repeatedly over the years, yet here it is. I was just over on WCCF and there was a whole gaggle complaining about this again, as in now. You'd think think some jr associate would take the initiative and present management with a suitable substitute. Why not get a discount and maybe a do a cross-promotion for using a certain brands pads?

    Plenty of youtube videos about this issue.... i personally VOID the warranty from a brand new video card replacing lame thermal pads for Fujipoly SARCON series and thermal paste AC MX4 , brands i trust....

    Opening up an EVGA video card and replacing the thermal pads doesn't void its warranty.

    Pretty normal after a bunch of heat cycles, take some iso alcohol and wipe it off, be careful around stickers however.

    Here you go! https://latam.evga.com/warranty/graphics-cards/
    :)
     
    I can confirm, opening up the card does not void the warranty. Replacing thermal pads also does not void the warranty. What WOULD void the warranty would be any physical damage caused during the process. Additional to that, liquid metal, if it causes a failure of the card, would void the warranty as well.

    Correct. For our warranty, the customer is responsible to ship the unit to us, and we will be responsible to ship the unit back. This way it is generally fair in terms of shipping. But as stated, removing the cooler, does not void the warranty of the GPU. You are free to replace the thermal pads as initially questioned.

    Anyway... i will keep purchasing Gigabyte products that HAVE RMA in my country since 8 years ago(oh... they leak oil from lame thermal pads too)...

    Don't think it would cost anyone but a few bucks to buy new pads if they so choose to. Oily pads are not hurting the card so why RMA the card? The next card would have the same pads. Buy new different pads if your bothered.

    I opened my GTX 1080 Ti today to replace TIM and clean card PCB from dust and oil. Gamers Nexus video help me a lot with all screws, but i can't clean PCB. I got cleanest alcohol i can find (99.7%), but i can't remove oil - it keep stay in place. Do i need something special for silicone remove? I want to get clean PCB to work with later (some thermal pads need to be replaced).

    @rusTORK

    The silicone was part of the thermal pad & is harmless to the PCB


    1) Silicone oil is very hard to remove.
    2) You do not have to remove it
    3) be careful not to touch your eyes on anything if you get it on your hands - wash it off or wear gloves
    4) There are electronic cleaner sprays. Follow - ALL -of the Directions including Safety - if you go that route.  Best to take it outside & use Eye protection & gloves

    I opened my GTX 1080 Ti today to replace TIM and clean card PCB from dust and oil. Gamers Nexus video help me a lot with all screws, but i can't clean PCB. I got cleanest alcohol i can find (99.7%), but i can't remove oil - it keep stay in place. Do i need something special for silicone remove? I want to get clean PCB to work with later (some thermal pads need to be replaced).




    If what you're trying to remove does not come off easily, it's probably NOT, oil from the pads and is likely the coating that is applied to the PCB. That is not supposed to be removed. It helps prevent corrosion.

    Cool GTX
    The silicone was part of the thermal pad & is harmless to the PCB

    Yes, but it also collecting dust which is not harmless for components.

    I don't think it's coating. Since some parts of PCB act normal when i apply alcohol on them (alcohol disapear fast and place look clean). When i apply alcohol on another parts (like zone under GPU, or VRM) - it stay black longer. I think it's leaked silicone from thermal pads.
     
    I already cleaned from dust front panel, both fans. Also washed heatsink with water (since it's made of metal), just have to wait really long when all water will gone (maybe a week).
     
    Maybe will be better to replace all thermal pads, but i don't know yet how thick they are.
     
    P.S. Brush didn't help a lot (i use very tiny brush), more results was with q-tips. It's collect silicon better... just need truck of it. =)

    I finally complete service for my GTX 1080 Ti SC2 Gaming. Founded proper cleaner to remove silicone (even pure alcohol didn't helped, but new one was like magic). Also replaced all thermal pads on front side on Thermal Grizzly Minus 8 Pads. Pads under backplate was in good condition so they stay on it's place. Assembling back is another story.
     
    I took some pictures during that time, so i may actually create small topic about it. Is it interesting? Admins and Moders opinion is interesting for me.
