I thought this product would be quite groundbreaking, but there's been hardly any coverage or reviews, hardly any builds I've seen it in. It's not even available on Amazon. It performs on par with the 1080 Ti FE, which I think is decent, although I'm not sure if that's simply a thermal limitation of having such a small a cooler on a 250W chip or if Zotac just didn't do a good enough job. They've been known to screw up coolers.
I think the fact that the card doesn't have a 0 RPM mode is a big disappointment. At idle with optimal power enabled in the nVidia control panel, a 1080 Ti consumes 11W. There's no reason for any fans to be spinning at that power draw, unless it's a reference design.
I also think there's an issue with a lack of cases that take advantage of this form factor. All the reviews I've seen have tested the card in cases that easily accommodate full-length cards. One of the 3 Newegg reviews is a guy who is getting it for his A4-SFX. Why...? Cases either only accommodate ITX cards (and those are a relatively small number) or full-length cards, or occasionally they accommodate both with trade-offs, like the M1. But this card is a size that is kind of neither here nor there. Clearly, there are a number of cases on this forum (CustomMod Mini 4L, S4 Mini) that fit the card perfectly, but we are a niche. So those are things I attribute the relative obscurity of the card to. I hope more cases get designed around it. I'm a little concerned that Zotac won't make it for the next generation if it hardly sells. I wish a truly ITX 1080 Ti was possible, but I don't see it. I wish ASRock made graphics cards, they could probably figure it out.
