Due to the lack of information available regarding the VRMs on the non-FTW cards I decided to test this myself on my eVGA 1070 SC black edition. This image is obviously much less accurate than whatever the review sites put out. I used a FLIR ONE (~$250, clips onto iOS devices to take low res thermal images), ran GTA V for 5 minutes, and then stuck my FLIR ONE into my case for this quick photo. Will let you guys debate the results. If anyone has the ability to do the same for a backplate card, I'd be curious to see how the presence of a backplate affects temperatures.

I took the backplate off of my 1080 ACX 3.0 card to put it under an AIO cooler with a G10 bracket (no heatsinks or thermal pads! NONE). The front AND back plates had to be removed to fit the AIO and bracket on.
I used a wireless IR gun to test each of the VRMs front and back while looping Valley at 2202MHz and power and voltage maxed (volts read 1.062 in software fwiw). The back posts of the VRMs (the solder joints that stick out the back of the PCB) all read about 60C. The front of the VRMs all read about 40C. Just a dinky little Kraken G10 fan blowing on them, and two big (and slow) 220mm fans blowing in from the case's side over the back of the card.
Not sure if that means the backplate is trapping all that heat on your card, or if your case doesn't have very good airflow. What I can say is that my 1080 ACX 3.0 (same PCB as the SC and founders) does NOT have that hostspot.

Good call on the airflow, I turned the fans on my case to max and the "hotspot" dropped to about 80C. More tellingly, it's also not so much a hotspot anymore, the airflow blowing parallel to the card is spreading it across the whole PCB surface which I assume is a good thing.

I have 2 front intake fans and one rear and one top fan so I have good air flow, so nothing gets a chance to get warm
i have seen video cards overheat in the past so I made sure the chassis i have now can handle it

It would be cool to get an official statement on the black edition from EVGA since, we cannot order the thermal pad, the whole situation is scaring me a little bit. Is it just because the black-edition is cheaper than the others hence less support ? or is the lack of backplate really that affect the VRM temperature ?

EVGA supports all SKU within the warranty period
if the card/PSU fail they will replace it

I have't pulled mine apart yet, but from reviews the backplate for the 1070 is essentially for protection, rigidity and aesthetic appearances only. There is nothing on the backside of the GPU or thermal pads to allow any heat to be transferred. It actually has small standoffs to keep the backplate away from the components. The only way heat can be transferred is via heat radiating off the pcb or through the standoffs.

 Here's an image showing results with more airflow. Not too shabby, right?

I suggest using lots of fans like said ^ and make sure all fans are clean and free to operate
Cards with higher power requirements need higher cooling

The GTX 1070 shouldn't really be considered a high power requirement card. It's a little bit irritating that I have to "baby" what should be a cool and quiet card (150W TDP, if i remember correctly) relative to its predecessors. 150W TDP would make this the coolest card I've had in a long, long time (have had GTX 260, 470, 760).
While (some) people are certainly over-exaggerating their problems, it seems clear the ACX cooler is worse than its peers (even if the temps are technically within spec).

196.75 was a bad driver and ever since I use an OSD when playing games to keep an eye on GPU temperatures, there are other sensors depending on the card my gtx 260s had lots of sensors as the GT200 is over 200W of power required and my cards are overclocked

Understand that this is the BACK of the card. The actual VRMs on the front must be running 100+c for the BACK of the card to read nearly 90c.

my evga card does not come with a back plate but by asus card does have one
both cards have dual fan coolers and are both around 150W or so maxed but in practice most games hardly warm them up
both cards probably benefitted from the swarm of fan i use, which likely has added to their service life considerably
my chassis uses 140mm fans but some higher end boxes now use 200mm and bigger fans

Wait, aren't you just proving my point that the ACX cooler is terrible? A "dinky little Kraken G10" absolutely crushes "The World's Most Efficient Air Cooler" [eVGA's words, not mine]

Disproving your backwards logic. The front is cooler and NOT hotter. Because there is a fan, or in the case of the ACX cooler, fans blowing over the top of the VRMs. Which is not the case for the back of the card.

LOL this is too rich. That reddit post is mine, I also cross-posted here. (can't post link due to my post count but it shouldn't be hard to find)
Not 30 minutes after I posted the thread here, bcavnaugh private messaged me: "You Could Have At Lest Posed what the Max Temp is, which I think is 102C You are causing more issue and problems on the Forum doing this, at least that is what I believe."
So let me get this straight bcavnaugh, you believe I'm "causing more issue and problems," yet you are quoting/reproducing my post here?
YES I Do! Their are to many Threads mixing up the two different main issues. Any yes you are welcome as well.

No. I agree with you the front is cooler and not hotter than the back. My point is that your VRM temps on the back of your card are 60C with a Kraken G10. I get 80C with the stock ACX. A lot of people complain that the Kraken G10 ignore VRM cooling but even the Kraken G10 completely outperforms the ACX when cooling VRMs...

The fan from the kraken G10 does not have a heatsink and fins directly above it causing an area of resistance. The fins on the cooler of the ACX will slow air down and need more fan power to push the air through to the vrm heat spreader. The kraken G10 has nothing obstructing the air to the vrm heat spreader.

OP, there are two different Black editions with the ACX cooler. (one has a slight overclock and is rated at 170 something TDP and the other has no overclock with a lower 150w TDP. Can you check your part number so that we know what we are looking at here?. I have the slight OC version and I am hoping that your card is like mine. If you have the 150w TDP version, your temps may be good because you are using less power in general.

Ok. That is the 170w TDP like mine. I guess I was lucky not to get one with a backplate.
