ARCTIC claims that the Accelero Hybrid 7970, which was designed especially for AMD's 7900/7800 series, has a cooling capacity of 320W and is up to 13 times quieter than the stock cooler. Furthermore, despite its large size, the Accelero 7970 weighs only 363gr.The Accelero Hybrid is compatible with the AMD Radeon HD 7970, 7950, 7870, 7850, 6970, 6950, 6870, 6850, 6790, 5870, 5850 and 5830, although with an MSRP of 179.99 USD/135.67 EUR we cannot fathom it being installed on anything less powerful than a 7870.Source : Company Press Release
