Hot Like the Sun and Wet Like a Rain: First Ever Water-Cooled Radeon X1900 XTX
Being one of the largest producers of ATI-powered graphics cards, Sapphire has opportunities to offer its customers pretty unique products that not only leverage reference designs, but provides some exclusive features. For instance, Sapphire has Toxic product line with improved performance and Blizzard family with improved cooling systems.
The most unique product from Sapphire at the show is probably its water-cooled Radeon X1900 XTX. The concept of the new Blizzard is akin to Thermaltake Tide Water: a heat-spreader is placed onto the graphics processor and the heat is taken to a special module which is installed just like a typical add-in card into computer cases.
Coolant is circulated with a 12V mini pump with superb reliability. Air is extracted from the case by a fan, passed through the radiator and vented out of the case at the rear mounting bracket. Two speeds of operation give a choice of lower noise or higher efficiency. (18dBA at 2000RPM, 26dBA at 2500RPM). The Blizzard cooler was developed in conjunction with Thermaltake and is exclusive to Sapphire.
Pre filled and sealed, the Blizzard cooler is easy to install and has removed the risks of spillage associated with most liquid cooling solutions. Industrial-grade rubber tube links the GPU block with the rest of the system to minimize liquid evaporation and is fitted with stress relief springs supporting the tubes against damage or distortion at their connecting points. Provision is made to top up the system when necessary, according to Sapphire.
While the Blizzard Radeon X1900 XTX will run at typical clock-speeds, it is expected to have better overclocking potential compared to the typical Radeon X1900 XTX.
