I received my 1080Ti Elite Black replacement card from EVGA today. As soon as it had it installed and setup, I ran Superposition once on 1080p extreme, then again on 4K optimized after a few minutes to let the card cool down. To my relief, the card completed the benchmark both times. It got a bit warmer than I would have liked topping out at 88 on the 1080p Extreme and 90 on the 4K optimized, but it did not stay there like the prior card. Temps ran mostly from 83-87 during benchmarking. The fans spun up and down as needed/expected. The 1080p benchmark--  To my surprise, the 4K benchmark ran better than the 1080P Extreme, but both still seem rather low to me.  At the moment, I don't see any red flags that point to a faulty card, but I thought that the 1080Ti was supposed to do five figures on Superposition with 1080p Extreme settings. During the test, I noticed the memory running at just over 6003 MHz. This is one of the 12Gbps GDDR5X cards, so I'm guessing that the memory speed is correct. I'm still a newbie at this. The 1080Ti's I've had are my first experiences with high-end cards. That's why I'm appealing to the experts here. Am I expecting too much from this benchmark? Where should I be looking to get the card up where it should be?

Wow 5Ghz, that's very impressive.
I should add that I run the 6850K itself on stock cooling, with stock clocks. I'm leery of overclocking and water cooling myself, but that is just me.
Here's my air cool config-
Case: Corsair Graphite 760T
2 x 140 mm intake fans in front
1 x 140 mm exhaust in top/back
I've got space for up to three more fans on top, and another position in the bottom. Would adding a couple of more exhaust fans in the top help me any with GPU temps?

Running a 6850K at 4.5 Ghz with a Corsair H110i. I never see over 55C with the fans at ~400 rpm or a low as I could get them to reliably resume from sleep. I think getting the heat of the CPU out of the case is key. The air inside your case is what is cooling your GPU. I would recommend using a CPU AIO on the top as exhaust. You really should be able to stay in the mid 70's with decent airflow and reasonable fan speeds (and less noise) on the GPU. 90C is still, really toasty. BTW I also run the CPU AIO fans off of a MB header with CPU temp control. Why use extra software?  But yes, extra exhaust would help, but that also needs to be balanced with intake flow. Ideally, you'd like somewhat more intake air than exhaust to maintain a bit of positive pressure in the case. A partial vacuum, certainly would not help temps. Those are my thoughts.

Your benchmark Hemi is what I expected my card to do. I am definitely concerned about the temps when they reach the high 80's to 90 like that. I checked out Corsair's water coolers, but right now I'm uncomfortable with the thought of all that water so close to my components. As far as the video card itself goes, I'm looking at this as a different matter from the second Green 1080Ti I had previously. That card had trouble even completing Superposition, sometimes failing hard. This card completes the test, but still runs very warm. From the way I describe the functionality of this Black card, does it sound like the card itself is okay? I know my case could definitely use better cooling, I just want to try to rule out a problem with the card itself producing excess heat and compounding the situation. For now, if I have one fan in the back, one in the top, and two in the front, all 140 mm, will that offer any help?

The GPU's within a few watts, pretty much all use the same unless you're doing some serious overclocking. Dissipating it, is what varies. That your card is stable even at those temps is a good sign. Okay, are those fans you have now, the stock Corsairs that came with the case? I just want to be sure of your current configuration.

Yes, i have two AF140L fans in front (white LED), one AF140 non-lit fan in the back. This is the original factory configuration.
I have up to three more AF140L I can put in the case, all of them with LED's. I don't expect LED's to matter, but I'm being thorough. The case itself is two-tone white and black, or Arctic White, as Corsair calls it.
I'm also considering the possibility of an aftermarket air-cooler for the CPU. I'm not arguing against water cooling being more effective, but I have to work within my budget and comfort zone. Is there an economical air-cooled solution for the CPU that will offer some benefit over the stock Intel cooler? Right now, I don't want to overclock, just trying to get some of the heat off the video card.
I remember reading now that Broadwell-E is a warm-running CPU architecture by default. I think that may be coming back to haunt me.

Nah, you've got a decent processor and they are not that hot at default clocks. I was just looking at the case. Are you using the hard drive cages or do you have those removed? If at the least you can remove the one blocking most of the air flow from the lower intake fan, that would help increase airflow toward the GPU a lot. Adding two low speed exhaust fans at top would help.

Okay, I've removed the lower HDD cage, and mounted the other directly under the 5.25" bays, leaving the lower intake completely open into the case. I've added the two 140 mm fans at the top, and ran the benchmark at 1080p Extreme again.  The two front intake are on the case fan controller, and I turned them on max. It's a two speed controller, and pressing the button made the LED's brighter, so I'm assuming they are at the higher speed. The top two and rear single 140mm exhaust fans are all connected to the motherboard. My motherboard is an AsRock X99 Taichi with BIOS/UEFI version P1.80. I'm still topping out around 90, this time over it-not good. This is puzzling, I thought maybe it wouldn't go over 90 with the extra airflow. Do I need to adjust the exhaust fans a bit?

I ran the Heaven benchmark and found the card peaking at 91-on a 10 year old benchmark, with two exhaust fans in the top of the case, and one in the rear. While the picture jerked a bit at times, and the card dropped as low as 11 FPS, it did not artifact or crash out.
It's hard to say for sure, but I think I've got a pretty solid card in a difficult cooling situation.
The very first 1080Ti I had was placed in a Carbide 500R, which had a dedicated 200mm fan in the right side panel for the video card. While temps weren't the best, I don't remember them being this high on that card. Was that large side panel fan really helping that much??

Yes it did.....the case was a Silverstone TJ09....so it was great for SLi GPU Cooling as it had a dedicate fan that would blow fresh air directly into the front of the GPU's (GPU Intakes).....but when I got a couple of GTX 480's (that ran very hot)...i cut hole in the side window and added a 200mm fan that blow directly on the Cards....it definitely helped lower the temps a bit.......

Don't get focused on the +** number on the GPU core - look at what the resulting number is The cards are not locked into their base numbers = all are different so the +** is different My card tops out at +65, I run it at +52. Max I have seen at +65 is 2050mhz, generally is 2025 at the +52 It is the resulting core speed you want to be looking at Going to +85 and crashing is not a mild OC that is a hard OC for that card on water. If you were running a chiller then yes it would be mild

This isn't quite accurate. While cards do boost differently the offset is the same on every GPU of the same model. +13 is one bin, not +5 or +15. The number you use DOES matter because folks get the mistaken impression you can adjust the clocks one MHZ at a time and you cannot. It goes in steps. They all go in the same steps at the same frequencies for the same model. The basic difference is in how many steps or bins you (meaning GPU Boost) can go. That is what varies somewhat and is controlled by GPU Boost. Even there, it is a pretty tight range for default boost clocks based on ASIC quality. Of course by controlling other factors such as temp, and to some extent voltage, you may be able to increase your clocks a bin or two or ~13 to 26mhz and override Boost behavior, or lock it using KBoost. Then there's going the next step where you are with dedicated water cooling. Sub 40C is really the sweet spot on these GPU's. Your last point is absolutely correct in that the important number is not the offset, but the actual clock speed.

I've been thinking about even more fans in my system. Let's suppose for a moment I had this case instead of the 760T-
https://www.corsair.com/us/en/Categories/Products/Cases/Graphite-Series%E2%84%A2-730T-Full-Tower-Case/p/CC-9011046-WW
If I were to drill holes in those side panel mesh cutouts and mount 120mm or 140mm intake fans in that side panel, with all the other cooling the same as my 760T, would that help cool the card?
The 730T is almost identical to the 760T in terms of overall case structure.
I'd say the first thing you should do is blow a big old box fan directly into the side of the case, (with the side panel off of course  ) and if that doesn't get your temps into the low 80C range on default fan speeds around 50-60%, I'd say you got an RMA that someone sent back for the same reason you feel like sending it back: Technically runs...but...not well. And also, using the box fan would tell you pretty quickly whether airflow is really your issue. I suspect not as there are many folks running a similar set up to yours that do not see 90C. So if the box fan doesn't do any thing, changing your case is not going to either.

Okay, I grabbed a box fan, and turned it up full on hi while running Superposition-I aimed it into the open case. I left the fan speed controlled by the Linux NVIDIA drivers . Here is the result.  Max 88 C. Also, I can see now that the P and the M LED's on the card are flashing red and green about ever second or so. The G LED stays solid green. P and M flashed throughout the benchmark. They're still flashing now. Does that mean something is wrong with the Power and Memory fans?

I located a compact mirror, and watched the fans during the benchmark. The GPU (nearest the monitor connectors) fan came on first, followed by the memory fan (nearest the case front), then the VRM fan (middle). The P and M LED's still blink red and green. Max Temp 89 (case open, ambient air + case fans only).
So the fans are working, but I'm not sure they're working right. I tried before with a box fan on high blowing into the open case, Max Temp 88.
I don't know what to think now. It looks like the card itself may not be cooling properly.

Couple of things that would be helpful. As you're using *nix, some things may not be as we expect. In other words, temps being reported by the bench, might not be the core temp. It might be the PWM or a memory temp. Your GPU has several temp sensors. If it's the PWM temp with default fan speeds for example, that is normal. With Windows we could just have you download the usual utilities and tell you exactly what is going on or at least have a better idea. If those are the core temps the fans by default should be running pretty fast. Audibly much louder.

I guess I can install Windows 7 on it. I bought a legit copy some time ago when I started building this PC. (I know, MS plans to kill security updates for 7 next year) When you say the usual utilities, do you mean EVGA's utilities?
In the mean time, should I be concerned that the P and M LED's on the card are flashing red and green?

I guess I can install Windows 7 on it. I bought a legit copy some time ago when I started building this PC. (I know, MS plans to kill security updates for 7 next year) When you say the usual utilities, do you mean EVGA's utilities?
In the mean time, should I be concerned that the P and M LED's on the card are flashing red and green?
Utilities like GPU-Z and yes Precision. You can get Windows 10 for like $14 dollars. Or just install an evaluation version. You don't have to activate it to do basic tests. https://www.goodoffer24.c...32-64-bit.html?acc=117

I'm trying to decide what to do about Windows exactly. Installing either 7 or 10 takes a long time, and I want to make sure my Linux install remains intact too.
I decided to submit a support ticket to EVGA about the flashing (P) and (M) LED's flashing red-and-green. They start flashing almost as soon as the computer is turned on, before any OS can even be loaded. I think they should all three be a steady green if the card is working right.

1080Ti SC Blacks....mild OC....cant get anymore than +85 Core without crashing......this is after about an hour of looping Heaven....
I switched to Water Cooling back in 2014.....unfortunately I seem to wind up with a stock pile of EK Blocks and Backplates after every generation .....
...and yes if your on air your going to want to maximize fans for your case...last Air Cooled build I had a added a 140mm fan to the side window to push cool air directly onto my GPU's.....it helped!!! .....bored a hole in the window and added the fan!!!
Don't get focused on the +** number on the GPU core - look at what the resulting number is
The cards are not locked into their base numbers = all are different so the +** is different
My card tops out at +65, I run it at +52. Max I have seen at +65 is 2050mhz, generally is 2025 at the +52
It is the resulting core speed you want to be looking at
Going to +85 and crashing is not a mild OC that is a hard OC for that card on water. If you were running a chiller then yes it would be mild
Of course what the Cards Boost to is what counts....in order to get a higher Boost Speed you have to increase Core Speed...thats a no brainer !!!! ...so yeh thats what Im focused on when OC'ing....AND of course the resultant Boost speed..... in other words +85 Mhz Core results in 2066 Mhz Boost......I still dont think its great OC at all considering the low temps I have under water...as in both Cards max out at 36c - 38c under full load....Id consdier it to be a moderate OC.....not great... +110 Mhz with a boost to 2100 Mhz would be a great OC...in my language ;)

Finally broke down and ran the card in Windows 10. The card performed a bit better. I'm guessing the Linux NVIDIA drivers aren't as optimized as those for Windows (This is my shocked face  ) First 1080P Extreme  Now, 4K Optimized  Note the temps are still a bit warm though. Even with the side off, 85 or 86 max was the best I could do. I had a phone chat with a couple of EVGA techs. I was told that 86 was sort of borderline, and as the card was stable they wouldn't recommend an RMA, although they would do one if I requested it. I was recommended to replace the thermal paste on the GPU die. I'm very uncomfortable about that thought, as if I damage the GPU EVGA won't warranty the card anymore and I'll be stuck with an $800 paperweight. If I go for the thermal paste, do I have to change every thermal pad at the same time? I also wanted my fellow user's input of new thermal paste. Does it sound like it would even help? Any particular recommendation for paste to use?

Ah....boy that's a tough one. If you have the dexterity and patience to build a model car, a GPU is relatively easy. If you're not very skilled and unorganized, I'd do an RMA. If you're going to do the TIM or paste, it would also make sense to replace the pads at the same time. There's several folks to walk you through if you need it and, there's usually someone around who has done one. It's just screws and couple of connectors. Windows 10 with Start 10 or Classic Shell is just like using Windows 7. 10 is pretty good now.

After some careful thought, I've decided to RMA the card. *sigh* This is card #3 now to have a problem.
I know it's technically functional, but it's just running too warm for comfort. Warmer weather would mean it will probably run even hotter. The best I could do with the card was Max 85. Even leaving the side open, it's still peaked at 86 on that specific run.
The card is too expensive for me to risk taking it apart and causing damage that would void the warranty.

I think I would do that too. If I was taking it part for my own purposes to change something, that's different. If I suspect a problem that might be fixed by taking it apart, I'd rather get a replacement than go to all the time and risk just to find out I... made it worse...

There's no guarantee that redoing the thermal interfacing would solve the problem. Even if it went perfectly. Everyone talks about the "silicon lottery", which I know is mainly related to overclocking. I've considered the possibility that a chip can lose the lottery in such a way that it just runs too warm no matter what is done-even at speeds the chip was intended to run. If the card were already out of warranty, I wouldn't have as much to lose at that point. This card still has almost 2 years on it, though. I can't understand why it is so difficult to get a stable, trouble-free card.
