Sparkle introduces GeForce GTX 465 and 470 graphics cards that are somewhat more friendly to the environment:
SPARKLE GeForce GTX 470/465 Graphics Card Uses Solderless Product With Green Process And Free Contact Process Cooling Technology

Ordinary Graphics card cooler more commonly use soldering process with tin-based solder alloys, the soldering tin will melt at a certain temperature, the binding layer is formed between the metal welding parts and tin atoms. When the graphics card starts running, the GPU heat transferred between the cooling metals must pass the soldering medium first. The SPARKLE GeForce GTX 470/465 Graphics Card uses Solderless Product With Green Process,making the cooling metal to fully contact each other, improving the ineffective heat conduction caused by traditional tin soldering and reducing the thermal resistance. Compared with tin soldering used by ordinary graphics card cooler, the Solderless Product With Green Process, has a higher heat transfer efficiency.

- With 5 high-performance copper heat pipes, the SPARKLE GeForce GTX 470/465 Graphics Card uses Free Contact process design, the heat pipes contact the GPU directly. This design allows the heat to transfer to the heat sink rapidly, effectively increasing the heat conduction, the cooling performance was significantly upgraded to maintain the stability of the system which is running efficiently.

Unlike the standard fan design on the GeForce GTX 470/465 reference card , the SPARKLE GeForce GTX 470/465 Graphics Card introduces the turbine thruster concept with large diameter 80x15 cooling fan that can produce stronger wind pressure during operation and quickly remove excess heat. Using the built-in PWM Technology, the fan automatically adjusts its rotational speed according to load balance for an even more effective reduction of noise during operation.
