The Taiwanese company applied a Diamond-like Carbon (DLC) membrane on the surface of video cards' cooling fins to realize the significant cooling effects of DLC, which display some of the unique properties of natural diamond. The membrane can help to quickly transfer the heat from GPU and video memory chips to the cooling fins.
SPARKLE R&D team found in the study that Diamond-like Carbon (DLC) which gradually been found in the past few years has many high-natures, such as high optical penetrating, high-chemical corrosion-resistant, excellent friction properties and good compatibility. In addition, Diamond-like Carbon (DLC) has a high heat conduction. General heatsinks rely on the electrons' movement within the metal (such as copper) to transfer heat via conduction. In DLC, phonons produced by the crystal lattice vibration lower the produced heat. Sparkle claims that the DLC dissipates heat four times faster than copper.
Sparkle said that it will use the Plasma Enhanced CVD (PECVD) technology to apply Diamond-like Carbon (DLC) membranes on the surface of video cards.
SPARKLE R&D team found that compared with currently available VGA cooling solutions, the Diamond-like Carbon (DLC) membrane can reduce temperature of a GPu by 5 degrees Celsius.
In addition, SPARKLE R&D team also found that the Diamond-like Carbon (DLC) membrane is a super-hard carbon coating that protects the radiator metal from scratching.
Sparkle did not say when the first DLC graphics cards will be available, since the technology is still expensive.
