Hot GPU and Cooling? Am I paranoid or doing something wrong?

I get the lego part of PC building, as do I get the compatibility part.

However, I'm at a relative loss with cooling and cable organization.

My graphics is a 1080TI SC2 from EVGA. It is driving 2x1080p with 1 usually being off.My concern is that many more intensive games push its temps to max of 85C, and I thought that I'd be able to play games such as ARK (a particular offender) at very high settings on more than just 1080p.... if not, I'm quite disappointed, as I was hoping to move this Pc up to 2 or 4k eventually.

I also tried it with Sniper Elite V2, with similar results regarding temperature.

Anyhow....
Here's my config.
NZXT Manta mITX Case
Win10 64x
Intel i7-6700k (stock) with H60 cooler.
675W EvGA GQ Gold+ PSU
MSI Z270i AC Carbon Gaming
16GB G.Skill 2400mhz .... something ram.

I tried replicating the cooling suggested in the post on NZXT's blog after google searching the best cooling options for this case; one major finding was that top exhaust actually stole cold air from the card and was worse overall.... but otherwise I'm not sure if I'm doing this properly.

Thanks for any help.

It's roughly ~20c ambient in room atm.

85C is fine, but your cooling setup is odd, try blanking off that top fan spot, and just have the one exhaust, you card is not blowing, it's sucking, so this way the two exits are via the back and the GPU rads. Typically exhaust is top and back, intakes are front, bottom and sides. Whilst you ambient is 20C, the inside of your case will be warmer than expected as you are intaking through a Rad, good for the CPU temps, bad for all other temps.

The fan profile on the card will be the ultimate determinant however, so you could just make a more agressive profile, I suspect it would settle to about 85C regardless of load (within reason) as that would be a balance between noise and cooling.
