Turned off the front right fan and covered it.   Both CPU and ambient temps went down by about 5c.  GPU remained the same.

Crazy difference in 4k, ouch. Doesn't seem right imo.

2k to 4k = double the resolution X double the resolution = 4 times the number of pixels and possible bandwidth restrictions. Less than 1/4 the performance makes sense to me.

So why in "real world" gaming where I play a game like BL3 and can average about 70fps in 2k and about 55fps in 4k,   it seems like a rather large differential in the uniengine test?

He's using Nvidia DSR factors, 2x is double the rendered pixels of his 1080p monitor (non-standard res, 2715x1527, not 1440p), while 4x is 4K.

 
Update: I was wrong about the ambient temperature.   I was looking again as my before and after data from HWmonitor, the six temperature sensors were way cooler after, anywhere from 5degrees to 30 degrees depending on the sensor.
 
Yet still didn't cool the card any? Hrm.

Glad to see those CPU temp improvements.  Depending how old that TIM was on the CPU, I wouldn't be surprised if the TIM improved the temps as well on top of a bigger heatsink.  Usually, you could see an improvement of 5c-10c on a premium TIM and or old dried paste renewed with premium.

I remember when I bought it I just bought the processor only and at the same time ordered a low profile noctua cooler and some Arctic silver.   About three years ago now?  So I guess that's how old the paste was.    I used MX-4 on the Dark Rock instead of the no brand paste that came with it.   
 
I notice you have custom loops going on.  Is it possible to turn off water pumps when not gaming? Or do the pumps just follow the fan curves you set?
 
Also finally, cos I have another crazy idea, does replacing the evga 2080 Super black gaming fans with something else void the warranty?    I am utterly impressed with the silent wings 3 fans on the dark rock,  I cannot hear the difference between it turned off and on silent profile with the case open and my face right up next to it.
 
I'm guessing the stock fans are 92mm?
 
 

Agree with bad tim, that happened to me once, and with an eVGA GPU, lol.... Well, tech it was the pads for the memory chips.....

MX-4 is amazing stuff which is what I use on all my stuff throughout the years.  The more expensive stuff might knock off a degree or two but honestly, they're all within the margin tbh.  The only time you should use specific high end stuff is if you're doing exotic cooling like LN2.  
 
As for pumps, you never want to stop the pumps, even on idle, the temps will slowly increase and you don't want an on and off sequence of things turning on and off to cool off as that can be an annoyance to some from audibles.  I keep my pumps running 90% to keep the flow at 1.0/1.1 GPM whether on load or not but every system differs dependent on the loops complexity.  Overall, my system stays happy.  The only thing I have on a curve are the fans based on water temps.
 
I wouldn't change the GPU fans from it's original cooler.  It would have to be in its original state if an RMA was ever needed the way it came new in boxx.  What you can do is replace the cooler with a AIO kit and with that kit you could change the fan that comes with the rad, previously stated here incase it was missed.

Thanks for info.   Aye I remember I was just trying to see if there was a way to avoid the AIO path and try quiet fans on it instead.   If I can't do it then it looks I'm going down the Kraken G12 path and then I can add whatever quiet fan I want.
 
Heh I'm even musing over this idea, but with an AIO:

That's the next step before you go into all sorts of exotic gyrations.  
 

You worry me sometimes...
 
I keep looking at the exposed PCB and no backplate and am wondering if I buy a custom backplate for my card model would that help any with cooling or is it just for looks?

You really don't know what you have until you check the TIM on your card and replace it.  

Okay so after looking at the link below (scroll down to disassembly) it looks at though the cooler and fans come off quite easily?   Fine I'll do a re-paste before other steps if it really is that easy.

And for the sake of comparison, does this look like the correct amount of tim or no?

Would adding tiny heat sinks to the chips help much, especially since I’ll have an exposed underside with the kraken G12

 
Okay so replaced the TIM on the GPU. Here are a couple before pictures.  It looks like large parts were not covered doesn't it?
 

 

 
Did 4k DSR tests on Unigine Heaven and Bl3 in built Benchmark.
 
Before results on both tests the card maxed at 75c and I could see a bit of throttling.
 
After MX-4 application, and I used a pea sized amount.  Same thing.  75c on both tests with same FPS averages.
 
Oh well.  Time to move on to the AIO.

 
Is the cleanup okay?  This is my first GPU repaste ever.  Here's how it cleaned up before I reapplied.  Does those tiny bits of old paste near the bumpy components matter? I was scared of cleaning that in case I broke something off.
 

 

 
I was thinking the same thing.  A few more questions please;
 
 
Pea blob or paint the paste all over the die this time?  Will covering the entire area of the pump heatsink help it any better? I notice it's way larger than the GPU die.
 
Why does NOBODY wear static wrist guards in all the instruction videos. Has static been removed from our universe now?
 
 
 
I do have to remove that black cover from the underside of the card right?   If so, should I cover all the VRM and RAM chips with little copper heat sinks? (Still trying to research a good thermal adhesive, heard horror stories of them falling off into the fan with weak adhesive.)   There's definitely enough clearance under the bracket
 
p400 radiator location options.  It will be a H75 120mm.  I wanted the kraken x42 but the price was insane. The tubes are only 300mm long, that can't reach the roof or the case front from the GPU.  Face it down into basement?  Exhaust behind Dark rock slim?(Will that get warmer due to the slim exhaust direction?)  There's even a possibility of an eternal bracket right behind the empty PCI slots.   But radiator should always be above the pump to prevent air bubbles right?
 
Will the exposed nature of the kraken make the coil whine louder?

Also be sure to be facing north during a full moon and do a couple voodoo chants.  Lol.

Bartender, I'll have what he's having...

 
So I got a H55 AIO connected.  Have two fans on either side of the 120mm with a push/pull config.  
 
Whereas I averaged 74c while gaming at 2k/75fps before the install.   It's now Averaging 51c while gaming 2k/75fps
 
I am calling this a WIN for my personal temperature goal but I still need to achieve the quiet goal AND I cant find a place to mount the Radiator in the P400a without spewing heat back in, OR getting heat spewed on it where mounted.
 
It just finally dawned on me WHY "the fans" were getting so noisy during 2k/4k.  Here I was thinking it was the 2080 cooler but now with the Kraken G12 and VRM fan set to my fan hub I knew it couldn't be that.    Listening very closely it's the BQ 750 watt evga PSU fan.     I was totally unaware they had fan curves??
 
If I purchase an evga GQ top of the line 1200watt PSU will that keep the fan speed low because it'll be way above what I'm drawing?
 
Thanks for all the advice so far, I would have given up and gone back to my 980 without you guys help.
