I can assure everyone that even without the thermal pads, the VRMs are still within spec and will not hurt your video card. It's not uncommon even on 700 and 900 series cards of all makes, models, and manufacture, including Radeon cards, to see VRMs running in the 95-105c range without problems.
The original concern is that the closer proximity of the VRMs to the memory on the FTW cards may have an affect on the memory temperature. Any reference design (anything that's not an FTW) where the VRMs are further away from the memory modules would have no concern in this regard. The Black Edition cards, as a reference design, would fall into this category. As others have pointed out, without the backplate to trap heat, the Black Edition is even less of a concern is this regard compared to models with a backplate.
We are more than happy to provide the thermal pads for these reference models as well as the FTW models as a way of easing concerns about heat. Again the article is specific to the 1080 FTW, but we want to address everyone who is concerned about temperatures.
