I may as well add this to the thread, because on the EVGA forums some mods / fan boys are trying to play down the issue, especially with the SC versions.
Guru3D tested 1070's with the VRM's using 3DMark Firestrike, using thermal imaging equipment. The EVGA 1070 SC Gaming hit 96℃ where the VRM's are located, that's between 27℃ to 39℃ hotter than three of it's competitor brand cards.
See below for results.
VRM = 64℃ - Gigabyte GeForce GTX 1070 G1 GAMING >>

Agree the evidence is clear there running hotter due to poor design (the missing pads)
there does seem to be a hell of a lot of defending evga and i can understand this as the majority are most likely evga card owners themselves..
This is understandable but what is not acceptable is the fact Evga can sell cards at these prices (UK) and we have these issues its totally unacceptable for such a small oversight missing the thermal pads ...but the fact is clear they have dropped the ball... they should have used thermal pads ...
Now what i hear a lot on the forums is this "my FTW temps are fine" ect but as we know its nothing to do with gpu temps and the VRM VRAM temps can not be monitored via software has to be done physically ....this can be very misleading for peeps...And this is where the problems lie if the end user could monitor such info via software i bet there would be more of an uproar seeing there VRM temps hit +100c and VRAMS over spec +95c ...
I have had 2 clients evga cards with me this weekend 1070 ftw and a 1080 both purchased about 2 months ago...these have now been fitted with my own bought thermal pads and i can conclude that doing so helps ..
I tested both cards to the best of my ability with only being able to use a Laser heat gun yes these are not very accurate but i was able to at least get an idea of the heat around the hot spot area.
Just in normal gaming for 30+ mins the hot spot area's where high up into the 91c for the 1070 with the 1080 being hotter at 94c this could be even hotter again not sure how accurate my heat gun is . this was on a open test case amb temp 18 / 19... now imagine in a closed case with poor air flow and higher ambient temps hell even in SLI what would be the temps of the hot spots for the top card well i dread to think.never mind peeps running over-clocks and to think FTW cards are marketed as over clocking cards too.
Now i did not want to run anything like furmark ect as i would imagine the temps would go even higher and these not being my cards i do not want to cause any long term damage ....So is it ok peeps getting these pads to fit themselves which again i find unacceptable for the price paid for these cards in which the end user is then having to finish the design off...Reminds me of flat back furniture..
the other problem i have found is that after gaming the fans would slow down very quickly... with the heat around the hot spot still being high and as the vrm's and vrams are cooled via air this is not a good design and i imagine a lot of users are using the standard out of the box fan profile i think this is set too low for less noise reasons .
Back to Placing the thermal pads on...
Removing the sinks both of heat sinks fins have scorched metal where the VRM's are located same as the photo i posted in my previous post... this should not happen period...
the results after the pads fitted much better 1080 76c 1070 71c with standard out the box fan profile ..
set a more aggressive custom curve the temps drop even further ...
So i will stick with my original theory that evga have messed up here with there design all from missing some simple thermal pads ...now what i am not sure about was it designed that way or was it a mistake who knows..
either way the price paid for these cards you would think they would have got this right.....
