done some benchmark.....
 
on heaven benmark:
200 to  240fps below 1920x1080
100 to 140fps for 2560x1600
40 - 60fps for 3840x1440
 
no overclocked.
 
 
 

What are your FPS @ 3840x2160?

absolutely sorry it's suppose to read 3840x2160 not 1440. btw after overclocked for that setting the benchmark would crash within 5 mins on the lowest OC tweak..

It be tuff but one thing I did that made a difference was adding a extrenal fan (120) blowing in from the backside of the case where the ports are on the cards. One would have to remove the blank slot plates from between and below the bottom card to allow the air to blow in. That's cool air blowing in for the cards heatsinks that lowered the tempts of both cards by 6c atleast. Might be more for someone else where there not getting any air circulation around the cards at all.

It all depends on your case if you can figure out a way to mount a fan there.. I just used a long zip tie and looped it threw the fan mount hoes and an opening on the case to hold it there.

Make sure the fan is the sticker side facing the case as that the direction the fan blows.

That's why I say evga's new pc case with there dual 120mm fans on the left side that exhaust or blow air into for your graphics cards would be great for hot air cooled graphics cards.

Other then that I ran with also a fan on the other end of the cards blowing air to them.. so I had air blowing at the cards from both ends.

Don't want a fan blowing at them from the side cause the fans on those cards blow strong air straight out from the side and down to the motherboard. So it would be useless.

Heat rises so good exhast put the top and strong cool air in from the front that blows towards your hot cards would be best..

No idea how the fans are setup in your case with that corsair cooler. Is that a single fan cooler for the cpu?? Mounted to the left of the cpu?

You need to test those cards ea with just one card installed at a time. Hopefully you can do that.

All you need to do is first thing disable sli in the Nvidia config. Then turn the system off. Flip the power switch on the back of the pc power supply to off.. and pull the plug from it as well just to be sure. Then hit the power button on the pc to drain all the remaining power stored in the caps from the PSU and mb.. you'll see it attempt to power up and the fans will slightly spin and shut off.. if you wait about 30 secs the power will drain from the mb and that wont happen when you hit the power button.

Then remove the side panel from your case. Remove the sli cable. Then pintch and pull the power cables from the graphics card your removing.Get a screw driver and remove the 1 or 2 screws holding the graphics card at the PCIE slot holder on the left. Now there's a small lever that locks the graphics card into the PCIE slot on the mb on the right side of the cards slot where it goes into the PCIE slot on the motherboard.. press that down and your card will then be free to pull straight out.

Might wana hunt for a video on YouTube for how to remove or install your graphics card if your confused.

Then plug the power cord back in to the PSU and power the pc up. Should not have to Install any drivers since you only removed one card.

Test that card.. it should run cooler now.

Right down temps.. idle and boost clocks and for the fun of it your benchmarks with just one card. And now you can test the cards max overclock. Don't bother overclocking the cards memory as it can limit your max cpu core overrclock.

Then when you think you've found the max you can get without locking up right that down.

My best benchmark is to use 3dmark firestrike. It's safe to use cause usually if your not stable the graphics driver will just error and then the benchmark will just end and no damage to whatever game is runing or lockup that needs a hard reboot.

Plus you can run a custom loop for whatever test. I like firestrike custom where I can select to loop just graphic test 2. So no loading in between changing tests for max heat.. if it will run that test for a half hour or more then you know your overclock is stable.

You can also buy 3dmark through steam.

So anyways when your done testing that card and also tested it with a few games for the black screen 100% fan issue, remove the card and swap in the other one and repeat all the tests keeping notes on that one.

Then when your all done and you noted each card by the last 4 serial numbers.. install the best card into slot one and the other in the other slot.

You really need to test ea card seperate.. it's also important cause you may find out one has a bad thermal goop job or a loose heatsink not making proper contact and could be why it's runing so hot.

Cool GTX
All ACX type coolers push about 80% of the heat into the case.  Your Case needs to be Big, your case fans need to creat enough airflow to push the heat out, faster than the GPU puts it in.
 
Around 50% fan speed some heat starts to exit the back of the card to the outside of the case; after the fan builds enough back pressure.
 
Otherwise you'll need the hybrid cooler $ or custom loop water cooling $$$$$

On cases I'd say totally evgas new dg-85 or 87. Turn those fans in the left side to blow in on your cards will fix your heat issue. Put the cpu cooler up top.

The case you have is fine as long as the HDD cage is turned to open to the front. I have the black version (called storm trooper, oddly) and my temps are beyond fine after turning the cage.

Edit:. Unless you just like a different case better. I mean only to say that it is very good as far as airflow and has great room to work within.

Hey Guys!

Thank you so much for your help and EVERYTHING! I have decided to just keep my pc as it is atm.... I am planning on upgrading my 6core to 8core (need to know how pricey will that be and if i have to change my Asus Extreme Rampage V mobo for it? also going to buy the evga dg-87 or w/e it's called :P but all this is happening probably early next year or mid next year when i move out from my small room to a bigger room as soon as my bro moves out the house. The DG-87 is really huge and i have no space for it but i really would like that case 'cuz i already have fallen in love with it. I can add those liquid pipes, l.e.d lights and still have so much room to work with :) AHowes! thank you again for your help! <3

I thought you had the 6850k now? You have the 6800k? Around here the 6800k is $400 and the 6850k is $600 so $200 more.

You would not have to upgrade you motherboard for that.. it will work with it and the 6900k and the 10 core crazy price 6950k as well.

I'm sure next year there will be newer cpus out and maybe new motherboards to support them.

Make sure to come on here and ask for some opinions on what to buy and maybe build this one yourself or (upgrade the cpu yourself! ;)

Yeah I'd be snagging that evga case myself but wow I blew way to much upgrading my rig and some extras to get my son runing his own rig so we can game side by side.

All that's left for me to do today is fill the coolant to the custom loop and hope and prey it fires up and all is well!

Make sure to register those 1080s (if you have ever not already) on evga as I believe you might get extra warranty time doing so.

Your case is nice.. I've looked at it a few times looking for a new case for my son but I'm forced to use an old mid tower I have for it.. no window :/

Get those fans optimized for better air flow and maybe add another fan blowing in from the bottom. More air in then out will cause a positive air pressure so less dust in your case. Just check those fan filters for dust every month or so.

Oh and remember.. without problems we would never learn anything!

The so-called "8 core" processor on the PS4 is actually made up of two quad core processors, and is as different as an apple is from an orange compared to your i7 6800k which is a true 6 core processor.

Yeah no worries comparing your rig to the ps4. I'm sure your rid would crush it! Literally.. just stack your pc on top of the ps4 and see what happends! Haha joking!

The 2 1080 ftw cards alone drop the smack down on that ps4.

Yeah I can't wait to start adding the coolant to the loop. But I gota get out there and cut the grass! It's been 3 days of solid rain here and it's super long! Takes me 2 and a half hours to cut it! Prob 3 hours with as long as it is having to stop and empty the bag so much.. but I'll be dat dreaming of my rig the whole time! Haha

haha sorry for the late laugh :P anyways!!!! I just installed the GeForce GTX SLI HB Bridge and mannn oh mannnn such difference, comparing to my asus ribbon sli bridge...eWW!! haha! my bechmark run on all ultra settings with 4k res running stable 40fps on stock clocked mode :) i am not even thinking of overclocking it because i am really happy with it! ahh the led light just adds an 'ouullalalala' to it :) i can't thank you enough AHowes! <3 All i am waiting for are 5 x 8gigs memory cards (2133mhz) and 1 960GB of SSD Drive by ADATA. and i'll feel complete.....maybe not....but just maybe... HAHA PCLIFE!

Wow full boat of ram!! 64gb! Styling no doubt! Me and my small 16gb ram hehe.

Oh the sacrifices I made upgrading my rig to also afford to buy a new monitor and drives for my son's rig as he wanted his first right and I basically had enough parts to build him one with my rig I replaced.

Oh well.. next time I'll be set and boy will he be all over me to upgrade to have my rig. haha
