This happens because Titan Xp’s fan speed curve is steeper than the other two cards.
How is it possible for a more complex GPU to operate at a higher frequency, temperature and power limit being equal? Well, the Titan Xp’s fan averages more than 2500 RPM, while 1080 Ti and Titan X both average less than 2400 RPM. All three cards end the test thermally-limited, but greater cooling performance lets Titan Xp bounce around at an advanced clock rate within that 84°C threshold.
Nvidia doesn’t need to spin Titan Xp’s fan as fast in this scenario. Because its 3840-core GPU hits its power limit at a much lower clock rate, the cooler doesn’t struggle to keep up. Instead, it’s the Titan X that strains above 2800 RPM by the time our 10-minute test ends.
Remember that 1080 Ti and Titan Xp both benefit from a freer-flowing thermal solution (at the cost of a DVI output). The design tweak appears to pay off here, though, under extreme duress.
Notice also that GeForce GTX 1080 Ti and Titan X demonstrate a sudden bump in fan speed, corresponding to the point where they overshoot their temperature targets. Such a rapid speed-up is audibly distinct. Meanwhile, Titan Xp’s clock rate starts lower as it immediately runs into a power limit, resulting in a slower temperature increase that never gets away from the fan.

I was thinking something similar while I was reading this. The Titan Xp represents the very furthest that the Pascal architecture can go. This current crop of cards from the 1050 to the Titan Xp will carry us to Volta's launch.
(wait, isn't there a card even smaller than the 1050? /shrug)
Edit: Why isn't this quote working?
Edit2: Figured it out =)
I have to agree. Even though I don't like them as a company due to some of their business practices, I have to give them credit for being a stylish company that really pushes it and completes their line-ups - I like things to be *complete*... :-)
I believe you are talking about the 1030. This isn't really a gaming card however, it's more geared for e-sports streaming and HTPC type builds.
This seems to be monster that would really benefit from that...
Yeaaaa. Thanks, but no thanks!
You know if someone handed you a Titan Xp you would stick it right in your box without a second though.
Yes. That's the one.
I mentioned it to illustrate that nVidia has a very wide portfolio with something for everyone. Pascal has been a terrific generation for nVidia.
