i7-7700K @ 4.5 GHz, Delidded
CPU/PSU fans fixed at 1800 RPM
NVIDIA TITAN X (Pascal) --> this card is essentially a reference GTX 1080 Ti

NVIDIA's default fan curves are so conservative that they limit the GPU boosting of their cards quite a bit. But even at 50% fan speed, the blowers are way too loud. Custom GPU coolers by AIB partners are so much quieter that I'd still recommend them despite the fact that they increase system temps by a significant amount.
Thanks for sharing that! I'd also like to add that based on my own anecdotal evidence, I am finding that using a lower fan speed (more quiet fan profile) reduces the CPU temps a little under gaming loads. This is kinda consistent with your results too. Just thought I'd throw my experience in as well.
With my FTW3, when I ran 100% fan speed during benchmarking, vs running the quiet fan profile, the difference in CPU temps with synthetic loads was at least 5 degrees C. The difference in boost clocks (no manual OC) between the 2 fan speeds was just 20mhz. IMO, a worthwhile tradeoff for the overall quieter and cooler (for the CPU) setup. The GPU can handle a few extra degrees of temperature
