Noise levels and temperature
Unfortunately the Zotac GTX 1080 Ti Mini is not semi-passive, which means it is clearly audible in idle.
Under load it is still pretty loud, but in comparison with some full-size models the noise levels are not that bad. It is slightly quieter than the Founders Edition under full load.
With 83 degrees under full load the GTX 1080 Ti Mini runs as hot as the Founders Edition.
