Temperatures
Temperatures are very low. Fan noise is, unfortunately, too high, and it would have been better to trade a few °C in higher temperature for lower noise levels.

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 that we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
