The latest HD 6970 in the Sapphire arsenal may have the same internal architecture and specifications as the reference model, but don’t let this fool you: this is no average card. This model uses a new design that includes dual 90mm fans with thin impellers that can move the same amount of air as a conventional fan at 10% lower rotation speeds, at least according to Sapphire. This effectively equals higher efficiency at a lower decibel range. Additionally, the dual fan design includes special dust repelling bearings that prevent dust from entering the fans' internal enclosure, prolonging the life of the fans.
The Dual-Fan HD 6970 also features a dual BIOS design which allows the user to switch from “Standard” and “Performance” settings. This switch allows the BIOS to be toggled between the two modes; in the “Performance” mode, the core voltage is increased to 1.2V while the fans are automatically set to a high performance profile, and the PowerTune rating is increased to 50%. This of course facilitates higher overclocking and ensures the Sapphire HD 6970 Dual-Fan will run at the top of its game.
Overclocking the GPU netted an additional 134MHz, which is just above a 15% clock frequency increase. The memory also overclocked well, as the GDDR5 memory didn't start to artifact until we tried pushing it beyond 1451MHz.
Sapphire always hit all the right marks, and continues to do so with this model . The Sapphire Radeon HD 6970 2GB DDR5 Dual Fan graphics card is extremely power efficient and is quiet to boot. Since Sapphire has kept the price point at the same level as the reference design, the Dual-Fan HD 6970 is a bargain.
