Temperatures

Idle temperatures are excellent and so is fan noise. No complaints here.

Temperatures under load are higher because of the increased heat output of the Tahiti GPU, but the temperatures are still perfectly safe even with overclocking taken into account, which increases temperatures more than on most other cards.

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.
