The SAPPHIRE HD 7970 OC Edition, which is factory overclocked to 900Mhz and features SAPPHIRE's new dual-extractor technology - Dual-X - a highly efficient multi-heatpipe cooler with dual fans providing quiet and very cool operation during normal operating conditions, and superb cooling performance even under extreme load. For enthusiasts wishing to maximise performance, a new version of the SAPPHIRE overclocking tool, TriXX supporting this latest generation of technology is available free to download from the SAPPHIRE website. TriXX allows tuning of GPU voltage as well as core and memory clocks, whilst continuously displaying temperature. Manual control of fan speed is supported, as well as user created fan profiles and the ability to save up to four different performance settings. Both of the SAPPHIRE HD 7970 models have a dual BIOS, allowing for further experimentation by the enthusiast. On the OC edition, the second BIOS is pre-programmed to allow a higher maximum overclock and more aggressive fan profile.
