Temperatures
Overall, temperatures are good. With 94°C, only the quiet BIOS reaches slightly higher temperatures under load. You, on the other hand, get very good noise levels with the quiet BIOS and are given the choice to focus on either temperatures or noise.

Important: GPU temperature will vary depending on clock speed, voltage settings,
cooler design, and production variances. This table just serves to provide
a list of typical temperatures for similar cards determined during TPU review.
Clock Profiles
Modern graphics cards have several clock profiles that are selected to balance power draw and performance requirements.
The following table lists the clock settings for important performance scenarios and the GPU voltage we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
