Personally facing similar, however my case is a bit larger so decided to go with new motherboard that has 2 slots in between instead of current 1slot where temperature on top card goes to about 85-88c max with the overclock applied.
Mind you the motherboard I chose is the X299 Rampage VI Extreme, which is an E-ATX board. Amongst the few I could find with 2 slots in between the GPU's. As it looks like you are using socket 1151, I am unsure if there are any motherboards with 2slot spacing, as it is a platform that I personally have not looked much at because of only 16pcie lanes. Top Asus motherboard for that socket might offer 2slot spacing. However as your case is cramped, you might have to see if you can fit it all properly first.

Good luck
Sustained temps of 90C will degrade a GPU, and heat cool cycles in an environment like that are not good for the solder on the PCB. The VRMs are also going to suffer as well with 125+ C temps to be expected.

Best case scenario is the fans fail early in 2-3 years. Worst case scenario is the cards die in that same timeframe. There are users on OCN who get 1-2 years out of an air cooled card - situations like this are highly suspect as to why that happens.


OP, I would sell the case and get something bigger and do a custom loop. A larger case with more airflow still won't work great with those cards unless you're okay with noisy fans.

True, I didn't think about selling the case.

I just ran battlefront 2 and the stats were great. temps at around 76, core at 1911, power limited to 80%... Couldn't get over 80 FPS or so... not sure what that's about.
I'd sell the case either way but have you tried full on positive pressure yet? My understanding is that you still have a back exhaust fan pulling air from the GPUs.
If you haven't repasted the cards yet that's usually good for 5-10c.
Another thing that could help is selling the AIO for a better tower cooler. It would ease up on the resistance and keep you from using the CPU heat to cool the GPUs. You'd probably end up with a few extra bucks and a slightly cooler CPU, if not cooler then it would be about the same. Most AIOs are only impressive till the radiator heats up, after that tower coolers are usually a tiny bit cooler.

The low frame rate could just be from SLI, try using just one card and see what happens. Could also be the diver messing things up, you can tweak it with NVInspector. SLI is hit and miss depending on the game. Some devs really put some effort into it but many don't since the biggest part of the market is using a single GPU.
Without seeing the load temps, clocks and load there's no way to really tell you why this is happening.

I can't return it. I gotta fix what I got.

Reason I have 2 1080tis is because when I'm not gaming, it was supposed to mine on nicehash. That's how I sold the idea to my wife... "hey hun, this thing can make us money when I'm not using it! It'll pay itself back in no time!"

So I called them today and told them what was going on... They xfer me to tech support and the guy is like, yeah why would you do that. That won't work well. I told them why on earth they are selling this setup then if it won't work... He said he's just tech support. Then I talked to cust support and he said, yeah nothing we can do. Sorry.... lol

I have the parts, and worst case I can just buy my own large case, but I'd really like to make it work with the SLIs in here. I might just buy the custom loop setup soon. I guess I like the challenge of making it work.

how does this benchmark look?

razorseal So I lowered the power limit to 80% and case open with a vornado fan blowing on the GPUs... Got my highest score yet on 3DMark at 16,000. I think that's a respectable number. Yet I'm doing 50-60 FPS on Battlefield 1... I think it's beyond the heat issue now

There is a good explanation on how to do it in the 1080ti club thread and running lower volts should help with temps. One of my cards is pretty mediocre so it only does 1660 at 800mv and 1850 at 900mv but that is still way faster than single card. You can always take more extreme measures if you want.
That's something I'd be willing to try. I have to find the thread.

8051 If your GPU is running at 90°C what temp are the VRM's are at? 110°? 120°? I hope not. Neither of those cards are getting decent airflow. The bottom card is just recycling its own heated air.
My 1080Ti gets driver resets at ~70°C but that's mainly because I'm overclocking it at 1.125V.

Maybe you could try reducing the core clocks of both cards and the core voltage.

white owl Having an exhaust fan will just make a low pressure spot there, meaning all that air coming in is just going to flow towards the exhaust fan. Another way to think of it is the exhaust fan will rob the GPUs of the cool air that should be pushed out the back.
Positive pressure from the front and top (assuming the bottom is covered) will force air out of the back of the case. Removing the PCIE covers will make that flow easier.
The only way to get heat out of a tight situation like that is to simply make the case have more pressure in it than your room does. All the GPU heat will be pushed out of the case if you do that.

RePasting the cards will help and so will reducing voltage as mentioned above.
