I upgraded my card with the hybrid kit and I'm confused about the temps. It usually runs 65-70c which seemed a bit high. So I swapped the stock fan to a BQ Silent Wings 3 fan which also got about the same. So I added another SW3 as a push/pull exhaust out the back (installed above the card with tubes on bottom) and this even got about the same (65-70). I added a slot cooler blowing more air on the card without any change. I noticed if I crank the fans up or down the temperature stays pretty consistent. I've also tried increasing or decreasing the pump (it's loud at 100% power but silent at 50%) but temperature consistent regardless of pump speed. The card isn't downclocking either.
 
Any idea what's going on? I have a Corsair h115i pro as intake and the CPU stays pretty cool (under 45c). 

 
To me it sounds like the heatsinks aren't making proper contact with the GPU can you give full specs and what software you're using to monitor the temps?
 

I'm using Corsair Link or MSI Afterburner. Both report the same temps.
 
Everything in my case is absolutely cool (all devices report < 45c temps) and running with the side of the case open doesn't improve temps at all. Nothing feels particularly warm either. I attached probes to the pump housing and on the VRM heatsink and neither get above 40c.
 
I confirmed the pump is working by setting it to 0 power and the temps climb to mid 50s even in idle. Setting power back to 50% and they fall back to low 30s idle. 50%-100% pump power makes no difference except noise. 
 
System is an i5 9600k, h115i pro CPU cooler, Gigabyte Z390 mobo, 2080 card, Corsair LPX 32 gb DDR4, CORSAIR RM850x PSU, and case is Corsair 275. Fans on the GPU rad are 2 BQ Silent Wings 3 in push/pull. Slot cooler is another BQ SW3 and a Noctua fan.

Pulled off the pump, clean it, and applied more thermal paste and now I'm sitting low 50s even on stress testing. You could tell looking at the chip that for whatever reason the EVGA default paste never made proper contact. It looked like only about 1/2 ever did. I gooped the paste on a bit liberally and everything seems fine now. 

Nice job! Yeah theirs no such thing as too much goop! I've been made fun of a lot about how much goop I use.. thick star pattern,, but boy it always turns out just fine!

The block will squeeze out the excess bit the most important thing is the 100% contact between the die and block and no air bubbles!
