The stock "LN2" 520W BIOS does still have protections in place - the card would've shut down automatically if it got any hotter.  You have to download the 1000W BIOS & Classified Tool to get a "fully unlocked" BIOS & that technically voids your warranty if they find out you used it.
 
I would suggest contacting eVGA Support/Customer Service (highly recommend doing so via phone) & seeing what they recommend, that pump issue should not be happening and it may indicate either the fan header for the pump is lose (rare, but it happens) or the pump is bad possibly.  They may ask if you're comfortable with taking the card apart enough to check if the plug in is loose or not - if you're not, RMAing it may be the only fix, if you are, I'm sure they can walk you through it.

Thank you, I will keep that in mind. It was just alarming to see a value of 109C on the core during one of my troubleshooting sessions  and was hoping the card to shut down but it did not. I will reach out to support this morning. I hope they suggest something DIY because I would rather save the back and forth shipping and being out of this card for an extended period. I am familiar with the KPE PCB layout and can do some troubleshooting myself.

Asked in another thread but I'll put it here for visibility - I have a 360 AIO on top as exhaust for CPU. KPE is up front as intake. 2 case fans bottom intake, rear exhaust. I notice that my GPU temps are great, but if I drop out and do something CPU heavy after a gaming session, my CPU temps are much higher than normal, I'm attributing this to not enough fresh air in the case, and the AIO liquid being hot from blowing hot air through the rad during the gaming session. A cold start my CPU temps are fine. 
 
SO - would any of these make sense: Rear intake to feed top AIO cold air? Top intake and hope the rear exhaust can move all the hot air from 2 AIOs? Front exhaust for KPE and hope the bottom 2 fans are enough intake (or possibly swap the rear to intake so all the air is back to front) 
 
Thanks!

I have a Lian Li O11D and gone through the same scenario as you. I placed temperature probes on each radiator's intake and exhaust. CPU radiator raises the air temp by ~5C degrees while GPU radiator shows 10-15C change. I ended up using the top exhaust for GPU radiator and side intake for CPU radiator. The GPU dumps too much heat to be placed as intake.

Sadly I’m not sure my CPU AIO can reach. How much did your GPU temps raise by doing this?

Not by much. I still sit at a respectable 55C full load under LN2 bios and solid 2100MHz on core

And to circle back - I'm using the OC bios, kept the fans on the KPE headers, and I will hit 472w of draw max on a looping stress test, so I'm pretty close to the 480 limit. I'm happy with those draw numbers. My old FTW3 would never break 370, drove me nuts.
 
Just got the card in yesterday so I have a lot of tweaking to do, but OC bios, +125 core is stable, and that keeps me boosting around 2100mhz in a stress test fully and my AIO heatsoaked. So far, so good!

I dedided to put my two cpu and gpu 360mm AIO radiator-fans exhaust so neither gets hot air from each other.

To keep case pressure i put as intake high speed pressure 2x140mm in the bottom and another one 1x140mm in the rear. All three at max speed.

The gpu fans at 80% when gaming. CPU don't get that much sleep so the balance is ok.

Testing temps i get gpu average around 50°C and CPU around 70°C (10900k@5.1ghz).

I use curve overclock in gpu of 1.043v at 2205mhz because more than this voltage i hit power limit.
Memory +1110mhz offset.

Its the first time I almost hit 15000 in Port Royale. No Classified tool. 14956 score.

I'm going to keep this as daily gaming.

Do you use stock fans or it's worth Noctuas A12x25?

Over this past weekend.

Congrats to Luumi!

White PCB best PCB my arse eh? lol  It's cool to see the Kingpin still trading blows with the HOF cards.

 
18,710 - nice.
