reading the tomshardware.de full review comparison , the EVGA has high VRM temp, but the Zotac has higher temp and Zotac didn't say anything about that.
Full temperature comparison:
Zotac GTX 1080 AMP Xtreme VRM 106.9c
EVGA GTX 1080 FTW VRM 106.8c
Gigabyte GTX 1080 G1 has hot spot 97.8c / VRM 82.9c
MSI GTX 1080 Gaming X has hot spot 96.7c / VRM 98.2c
Gigabyte GTX 1080 Xtreme Gaming VRM 83.2c
Palit GTX 1080 Game Rock hot spot 82.6c / VRM 76.9
Galax GeForce GTX 1080 HoF VRM 75c
Yes, but only in Furmark. If you look at the Zotac run on Metro:LL, where the FTW cards keep scoring over 100 C, the temps are down to some of the better temps in the field: 88,9 C
It's a very logical result of the Zotac AMP! Extreme having a 270w power delivery instead of the FTW at 215w. Furmark maximizes the power draw to whatever the board can push, but is not a realistic gaming load. The much lower VRM temps on the Zotac actually show that the cooling is well designed around the normal TDP limits of Pascal, and that its VRM section is heavily over engineered. Pascal BIOS will never allow the card to draw 270w, so the only reason you'd ever see VRM temps over 100 C on the Zotac AMP is when you are using modded BIOS and hardware volt/TDP bypass mods - which immediately voids the warranty.
In addition, if you have been paying attention, it is the GDDR5 next to the VRM section that creates issues at high temps, not the VRM itself. Even though 100 C is hot, its usually within spec for VRM which is rated for 105-120C (or more), while GDDR5 is rated at 95 C.
And then you keep the EVGA solution WITH the added thermal pads next to this, and you can see why there's reason to say ACX 3.0 is a crappy cooler design.
