Conclusion
Zotac's implementation makes it hard for us to lump the GeForce GTX 1070 Ti AMP Extreme in with other 1070 Tis, which should all perform and behave somewhat similarly due to Nvidia's fairly strict guidelines. This one isn't like the rest, though, due to fan control that doesn't seem to care whether you're sitting idle or torturing GP104 with FurMark. It's nice that lots of airflow translates to low board temperatures, but there are better ways to achieve this.
The statement we received explaining the fan behavior isn't particularly convincing. Instead, we're left with a design mishap that casts a dark shadow over a board that otherwise shows lots of potential. That's really a pity, since the GeForce GTX 1070 Ti AMP Extreme doesn't seem cheap at all, and instead exudes solid build quality.
You'll also want to keep this card's weight and length in mind if our noise measurements didn't already turn you off from considering it. Of course, anyone with a bit of spare time and the right tools could just unscrew the top cover and install their own fans. But is that really what you want to do after purchasing a high-end graphics card?
To drive one final nail into the GeForce GTX 1070 Ti AMP Extreme's coffin, Newegg currently sells it for $500. There's no sane reason to spend that kind of money on any GeForce GTX 1070 Ti with 1080s starting in the same neighborhood.
