SPARKLE introduces custom GeForce GTX 465 and GTX 470
Sparkle today announced two brand new custom graphics cards based on NVIDIA’s GF100 – GeForce GTX 465 and GeForce GTX 470. The graphics card cooler used on these cards feature Solderless Product With Green Process and Free Contact Process Cooling Technology.
Compared with tin soldering used by ordinary graphics card coolers, the Solderless Product With Green Process has higher heat transfer efficiency: this process makes the cooling metal to fully contact each other, improving the ineffective heat conduction caused by traditional tin soldering and reducing the thermal resistance.
Using the Free Contact Process Technology (which is essentially just heatpipe direct touch technology), the five copper heatpipes are in direct contact with the GPU core. This design enables heat to transfer to the heatsink rapidly, effectively increasing heat conduction, and hence cooling performance.
SPARKLE says the large diameter 80×15 fan used produces a stronger wind pressure, thus removing heat transferred to the heatsink more effectively. Fan speed is PWM-controlled; it is automatically adjusted according to the load levels and temperature.
The SPARKLE GeForce GTX 470/465 Graphics Card delivers all the benefits of the advanced 40nm process from TSMC, a high speed GDDR5 memory interface, and full DirectX 11 support, possessing considerable power improvements compared to its predecessor. It uses the GTX 470/465 core with 448 / 352 stream processors and a 320-bit / 256-bit memory interface with a 607MHz core clock and 1280MB of 3384MHz / 1024MB of 3206MHz GDDR5 memory.
