Noise levels and temperature
We measure the noise levels at a distance of 10 centimeters (4 inches) inside a noise-proof box, with the measuring device directed diagonally at the graphics card. The load-test is the average noise level of one minute, measured during an elongated 3DMark Fire Strike Extreme run, after warming up the card for about 10 minutes in the same benchmark.
The idle noise level of the Nvidia GeForce GTX 1080 Ti is a good deal lower than some of the other Founders Editions, just like with the Titan X (Pascal). The card is rather noisy under load, which is to be expected given the power draw. Despite its noisiness, the Founders Edition cooler doesn't cool the card particularly well: it ends up at 83 degrees Celsius.
