Temperatures
Under-load temperature is heavily predicated by the cooling used. We set the Corsair Graphite 600T's fans to 'auto' (silent) in the BIOS, resulting in minimal airflow and near-silent operation. Running the same test again with the fans manually hitched to a 'medium' setting reduced the Just Cause 2 temperature to 76°C. Switching them off altogether resulted in a maximum temperature of 82°C.
Whatever the setting, we feel comfortable in stating the HD 6670 Ultimate won't overheat unless your chassis has very poor airflow and is hugely space-constrained.
