So let me describe my situation to you. I have the 1080 ti sc2 hybrid. For as long as I have had this card, I have been having trouble with its temperatures. I mean bad. 68 degrees in ruiner with only 60% utilization and only reason why its at that is because i have set a cap at that temp. It is rather annoying because I have paid a premium to have a hybrid for lower temps, only to learn know that isn't always the case. This isn't even the highest temp I have had. 86 degree Celsius while playing man of medan??? The game is literally a movie and still wasn't at 100% utilization. Frustrated with the temps, after two years of playing (yes I know it seems like a long time to deal with a issue like this, honestly haven't had time to game much due to school) I decided to send in a RMA. Somehow they have stress tested it for a hour, and the highest temps they can get is 46 C. They let me know that they have replaced the hybrid kit and send it back to me. So i get it back plug it all back in the way I have it, and my card still somehow reaches the same temps that I had before. At this point, I really don't know what to do. I've had it set up as a exhaust on a friends pc and still get the same results as I have it currently set up rn as an intake.
 
If you want to know my setup it is:
 
CPU: i7-7700k
CPU Cooler: Noctua dh-15
Motherboard: ASUS Z270E
GPU Radiator Position: Set in the front as a intake, have tested it as an exhaust and the difference is next to none so I have it in the front due to cooler
Case: Fractal design r5
 

I know the reviews say otherwise, but the front of that case looks extremely chocked for air. Also I am going to assume that EVGA tested your GPU and Hybrid Kit on an open air bench. Honestly I am not surprised by the temps that you are getting in that case seems about normal too me... What happens if you stress the GPU with the door on the front of the case open and the air filter removed? Also you may need to just increase the fan speeds, once again I am sure EVGA tested it with fans at max. Do you have any other fans on the case besides the ones on the front RAD? If yes where are they located and are they intake or exhaust fans?

To jason, sure I am testing it in a closed system, but the testing I am doing is with evga stock fans plugged directly into the gpu so it definitely runs at 100%. I have tried it at the back in another system with the same results. With a hybrid card, i just expected it to usually stay at least below 60 with 65 being the absolute highest. With stress testing the card myself, for only 30 mins, with fans set at their max, i was still hitting well over 72 C.
 
To sparetime, I have done everything you said but I do think the amount of case fans I have are lacking when I think about it. But at the same time, this isn't the only rig I have tested this in. In this rig I use primarily I have three, one in the back and front, and another on the side

Are those fans intake fans or exhaust fans? Honestly in this case I would run that radiator in the front of the case and set it up so that its blowing air into the case. Than I would use just a SINGLE fan in the rear of the case running as exhaust... This is probably going to be about the best that you can do in this case.  More fans in this case I believe will end up either not helping or more than likely hurting performance.

That is literally my setup
What the setup looks like (sorry for poor lighting):

Yes I have ran it without the side on for the stress test i did when they sent the card back to me
To jason, the noctua cooler prevents that from happening. Also I have already tried what you said, the difference was about 3 degrees cooler.

Looking at that picture it just looks chocked for air... removing the side panel will do nothing to fix that issue. You need to open the front door of the case, remove the air filter, and remove the side panel and see what happens.

Also what is the temp of the room you are in?

AIO as exhaust has to deal with all the heat from the CPU
 
Room Temp ?
 
What are the Current case fans & blowing In or Out ---> what RPM & how are the fans controlled ?

As for it being chocked by air, I think you might be right. There is a grill on the side of the case  that allows air to come in so i wouldn't say its too awful 
 

This is simply a problem of not having enough cool air flowing through the GPU rad, period. I'm sorry but the R5 is bad for air setups and is better suited for water cooling. About the best you can do here is get yourself an AIO for the CPU and mount it as exhaust on the top and mount the GPU AIO as exhaust in the rear and of course intake flow in the front.  That's my suggestion. An air cooler in a case is not conducive to low GPU temps, particularly one that has restrictive intake flow. Personally I ditched the stock Hybrid fan and run two Scythe AP-14  push/pull exhaust at 90% off a motherboard header. I idle at 23C and max out at 47-50C overclocked to 2038 after hours of gaming.

Do you know where the Scythe AP-14 are sold at? Seems out of stock everywhere i look
