So I have had a few issues with my PC running in SLI. Finally determined that one card was bad and its on it's way back but in the mean time I have been just using one card which I just cleaned then reinstalled into a PC that I basically just rebuild as I was determined to find the SLI crash problem. SO I replaced the motherboard, put in a 1600 P2 power supply from the 1300 G2 I had before and added new RAM. Started the PC and everything seemed to be running great. THEN I ran a benchmark and there I could see my temps were way to high and my FPS was around 20 to 40fps. I could see my idle temp of 35c instantly go to 80c or even 86c degrees during the bench. Not even slowly but almost instantly spiked. I can figure out what would make a card spike like that and I think 35c idle may be high as well. If I plug in my second 4k monitor to the card run both the idle goes to about 60c. I took the card out and thought that maybe it was soft wear related so I reset the PC Bios and Windows put card in and it was still happening. Took the card out and changed the thermal past to another brand and added a little more, Put card in again and same issue. Is this card dead? Do I need to RMA this card as well? It seems to work fine except the horrible FPS and temps under load. Just to be clear my, my watercool set up is WAY overkill. I'm running two 480mm radiators in my PC. One for the CPU and one for the GPU. (Yes I know it is overkill. I did it for looks of the PC, not extra cooling) -MCI MEG ACE Z390 Motherboard -Intel i9-9900k -EVGA 1600 P2 power supply - (currently until second card arrives) 1x EVGA RTX 2080 TI Black Cards - 4x 8gb G-Skill TridentZ 4000Mhz Ram Everything is basic settings at the moment. SOLVED: Was exactly the problem. Not making contact due to Thermal pads being to thick. I put it all back together today with thinner pads going from 1mm to .5mm as shown on EK diagram on their web page and poof! Now Idle temps sitting at 27c and a full run of Fire strike temps reached a max of 39c. CRAZY how .5mm was keeping the block from making contact.

Sounds like a bad thermal paste application, I would take the block of and reapply your thermal paste, also make sure your coolant is actually flowing properly.

I tried this once. May try again. The only other thing I changed was the thermal pads in the card from EK stock pads that came with the block to Thermal Grizzly Minus pads.

Verify the flow rate on your system, if you can't feel the heat from the radiator then the water isn't moving. Make sure the pump has pressure, then take the GPU block apart to clean it and make sure nothing is building up in the fin grids. It can also be something as simple as a CPU block oriented 90 degrees the wrong way preventing water flow for the entire loop.
Have water, will cool.

Have flow. I can see it visually and have flow meters in both loops. What i am thinking is I used 1mm pads in the blocks when I changed the paste and EK provides both 1mm and .5mm pads precut pads that I just changed out. (I just wnt back and re read the EK manual) So basically I'm using 1mm pads in places I had .5mm pads before. I think this may be preventing a good connection between the block and GPU. New .5mm pads ordered and Kingpin thermal compound. Will have them both today. Hope this solves my issue with the heat.

I read your first post above and immediately noticed the issue. But it looks like you figured it out in your next post, before I could say anything. I ran into a similar issue. When I first installed the EKWB on my 2080 ti FTW3 Ultra, I was getting idle temps around 35c and it would quickly climb to the mid 70's under initial testing. I went back in twice, looking for issues but didn't see anything glaring back at me. But on the 3rd time opening the card back up, I re-read the instructions very carefully and realized that I used the wrong thickness pads in certain areas. I re-applied the correct sized thermal pads in the proper areas and re-mounted. This dropped my idle temps to around 24-26c and now the temp almost always remains under 40c (max I've seen is 42c), even after benchmarking for an hour at +1000 mem and +130 core. It's crazy the difference 0.5mm can make! Also, I'm sure you're already aware, but make sure to tighten screws from the area right around the core, slowly working your way out. This will help ensure proper pressure on the die when everything is all buttoned up. It's amazing how finicky temps get unless you install these water blocks perfectly.

Sn0w's right. That's most likely your issue right there. Some of these blocks are specific to the size pad by design. If they are too big, the cooling base won't make great contact with the GPU or if it's too small, you might risk damaging the GPU. Stick with the same spec pads.

Part of installing your water block is Testing the assembly Assemble & confirm proper contact with your Thermal pads & that the GPU shows proper contact in the thermal paste Water block is either Not sitting Flat on the GPU, Gap is too big (poor contact) between block & die - or - you did not cover the entire die with thermal compound

You sir are correct. It was a bad pad thickness.

Glad you got it sorted out! When it comes to spacing it either works or it doesn't.

Mike, i think i am having the same problem. Hopefully you see this reply here. My question to you is, when you say you went from 1mm to .5mm pads as referenced in EK's diagram, do you mean that you replaced all of the thermal pads with .5mm pads? In their diagram, they reference placing 1mm pads in certain areas and .5mm pads in other areas which is what i did on my card but i am also seeing high temperatures on my 2080ti with an EK waterblock. Let me know because i intend on trying switching all pads to .5mm. Thanks!

I used the .5mm in the places they recommended and 1mm also where they recommend. So I used two sizes in the card following their diagram Of where to put each one. This fixed my issue with heat.
