Temps were good to begin with but SLI always raises the top cards temps. My max temp i have seen on the top card during fire strike bench was 80c with a custom fan profile. I used Cool Lab's Liquid Pro on the GPU & Fujipoly Extreme padding on the mosfet / memory plate and it made a nice difference on both.
 
Fire strike went from 80c to 72c  on top card and you can feel the difference on the mosfet / memory plate through the back plate which screws into it. If I had the cards in a case with a fan hitting them i am sure they would go even lower.  8c drop is good for liquid pro but it also shows that EVGA was using a good TIM on there GPU to begin with . The highest temp i can get on real world gaming in 4k dsr is 69c now and for SLI that is a great temp!. Some photos below. 
 
****for anyone who is going to do this EVGA rep told me on the phone that the thermal pads on the plate were .5mm they were incorrect and they are 1mm padding******
 
Good thing i had 1.mm pads from a prior job. Since frozen cpu had shut there doors it took me a while to find these pads. Performance PCS had them in stock. Most other only had the standard Fujipoly and not the extreme version.
 

 
 

great job, nicely done.
I'm thinking of doing the same with my GTX970 FTW since I bought it 3 months a go but I still didn't find time to.

Thanks man. Totally worth it.....

Very nice,69c for Sli is pretty good temp.

yes, it is.
by the way how did you manage to get the SMD parts area around the GPU so clean?
there always tends to be some tim left between them, I'm afraid to brake the small parts.

A soft bristle tooth brush and alcohol works for me. Just need to be gentle and clean off the TIM on the brush between strokes.

that's a very good idea 255killer, I'll try it out for sure - thanks.

The big difference between the brand i use and the others is the Thermal conductivity the one you listed is 1.5 W/mK  and the Fujipoly Extreme padding  is 11.0watt/mk si it is kind of like using liquid metal vs arctic silver....thank you though...

Please forgive my Poor English, it is only my First Language.

To be honest when I cleaned the GPU i caused the old tim to hit the small capacitors on the side. EVGA did use it somewhat sparingly compared to other manufactures... I just used a swab very lightly and took my time... I would be to scared to use a bristle brush but then again i never tried it...
