Today Asetek announced the availability of its liquid cooling system for the new nVidia GeForce 9800GTX and GeForce 9800GX2 graphics cards. Asetek is the first liquid cooling solution developed to exceed the stringent thermal performance, low noise and daunting reliability requirements demanded by Original Equipment Manufacturers (OEMs).
The graphics GPU power budget is constantly increasing as enthusiasts and professional workstation end users exhibit an insatiable desire for higher frame rates and resolution. Thermal management of the graphics card is an ever increasing challenge with every new generation of Graphics Processing Unit (GPU), often at the sacrifice of acceptable fan noise.
The factor limiting the maximum GPU frequency of operation is often the thermal limitations of the graphic card. This inability to provide the GPU and board devices with sufficient thermal margins limits the board’s ability to be over clocked and often the fan noise becomes objectionable as air cooled systems strain in an attempt to remove the generated heat.
Asetek’s cooling solution approach eliminates these barriers utilizing hybrid cooling technology whereby the GPU is cooled by a liquid cold plate while the memory and power sub-systems are cooled by forced air convection.
