Why do the other cards not show such hot spots then?
The founder's edition shows no hot spot: http://www.tomshardware.de/nvidia-geforce-gtx-1080-gtx-1070-grafikkarten-roundup,testberichte-242137-10.html
EVGA makes great products, I've been buying them for years, but there is definitely a hot spot over the VRM/memory area that seems to exceed the safe range for those components...and I can't even imagine what it's like if someone's case isn't ventilated right or kept clean.
I do not have a way to measure these hot spots, nor am I an electrical engineer that could figure out why adding twice the amount of VRMs would cause a hot spot.
The SeaHawk (MSI) has a relatively hot VRM section compared to the FounderEdition, and they utilize nearly the same VRM section with a few minor differences.

http://www.tomshardware.de/nvidia-geforce-gtx-1080-gtx-1070-grafikkarten-roundup,testberichte-242137-4.html If I had to go with best guess, the heat plate is not dissipating enough heat due to the low fan speeds and strive for silent operation.
The Galax HOF would be a good example, as the PCB contains extra VRM kind of like the FTW:
http://www.tomshardware.de/nvidia-geforce-gtx-1080-gtx-1070-grafikkarten-roundup,testberichte-242137-6.html Notice that the heat plate has fins to assist with dissipating the heat, and the cooler utilizes more fans.
I also notice that they utilize furmark, which NVidia black listed because it was killing GPUs. I mean, if they are going to torture test a GPU, why not use a program known to overheat and kill GPU's?
