Cooling firm Asetek has announced the availability of a liquid cooling system for the NVIDIA GeForce 9800 GTX and GeForce 9800 GX2 graphics cards.
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.
• Performance – The maximum performance and ability to overclock the graphic card is dependent upon the thermal design providing low device temperatures. Asetek’s thermal solution reduces the GPU temperature by over 25°C compared to solely air cooled designs providing excellent margins for higher clock speeds and improved graphic performance.
• Noise - Annoying noise which has been increasing in recent years is virtually eliminated. Even in hot ambient conditions, the noise level of the card will never exceed 22dBA, about the level of a quiet whisper, where the typical air cooling solutions are approaching 50dB(A), about the level of a loud conversation or many street corners.
• System Thermal Management – The traditional air coolers dump a lot of the graphic card heat in to the chassis heating up other components and increasing the overall noise level. With Asetek’s liquid cooling the heat from the graphics card is exhausted outside of the system chassis allowing other components on the motherboard to operate cooler and with higher reliability System fans have less work to do and are able to run slower reducing system noise still further.
