The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 25c – a comfortable environment for the majority of people reading this.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.
The card actually runs cooler at the higher 1,000mhz core setting which is due to the more aggressive fan profile. At 950mhz when gaming the card hovers around 66c when gaming, which is a 14c improvement over the reference cooler, substantial improvements. Bios 2 setting raises the fan profile a little which lowers the temperature to around 63c when gaming, a 17c improvement over the reference design.

Hi Ryan. Next to the crossfire connectors is a little switch. Power the system down, flip the switch. reboot.
Done.
