SPARKLE Proudly Announced Diamonds Sputtering Technology for Video Cards

SPARKLE Computer Co., Ltd., the professional VGA card manufacturer and supplier, today proudly announced Diamonds Sputtering technology for video cards, which raise the bar for video card cooling technology.

Now with more and more advanced relative technologies, the performance of video cards is getting stronger and stronger, there will be more heat generated by video cards, which significantly impairs the life expectancy of GPU and video memory chips on video cards. Video card companies have a lot of programs come and go to solve the problem of heat dissipation. The most commonly seen in general is the use of fans with cooling fins to do additional cooling. in the early days, the cooling job can be done simply with a fan or cooling fins, but in today's graphics cards with more intense heat than before, the cooling job must be done on the technologies not the same as before, not just rely on the fan and cooling fins. Video card companies must go to find some relatively new method to solve the problem of heat dissipation.
With a strong R&D team, SPARKLE introduced Diamonds Sputtering technology, which plate a Diamond-like Carbon (DLC) membrane on the surface of video cards cooling fins to realize the cooling effects of DLC. Diamond-like Carbon (DLC) 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) also has a high heat conduction. General heatsink is relies on the electronics movement within the metal (such as copper) to do heat conduction. The diamonds do heat dissipation four times faster than copper, it relies on the phonons which is produced by the crystal lattice vibration, to bring heat to lower temperature places. Diamond-like Carbon (DLC) can achieve both functions at the same time, that is, transferring heat to lower temperature places with both graphite metal bond and diamond insulation bond (the covalent bond) . Apart from this, Diamond-like Carbon (DLC) can transfer carbon surface heat (atomic vibrations) into the infrared radiation of electromagnetic waves in bold (Black Body Radiation) , directly to the air molecules.

SPARKLE R&D team is now using the leading technology of Plasma Enhanced CVD, (PECVD) for SPARKLE graphics cards, to plate Diamond-like Carbon (DLC) membrane on the surface of video cards cooling radiator, providing unbeatable cooling effect, significantly raising the heat transfer speed from the GPU and video memory chips to the cooling radiator. With tests, SPARKLE R&D team found that compared with no Diamond-like Carbon (DLC) membrane, Diamond-like Carbon (DLC) membrane can reduce the value of thermal resistance of the radiator about 0.05, the radiator temperature can be reduced by 5 degrees Celsius, greatly accelerate the heat conduction from GPU and video memory chips.

In addition, SPARKLE R&D team also found that, in addition to outstanding cooling effect, the Diamond-like Carbon (DLC) membrane is a super-hard carbon coating, it can protect the radiator metal from scratching. Diamond-like Carbon (DLC) membrane can isolated the air to avoid the thermal conductance reduction of radiator due to oxidation (such as the formation of Cu2O or Al2O3). Diamond-like Carbon (DLC) membrane can also protect heat sinks from water vapor or acid-base erosion. Therefore, Diamond-like Carbon (DLC) membrane is the best option for extending the service life of SPARKLE graphics cards. Because the current cost of this technology is still high, SPARKLE will consider the appropriate application step by step according to the real situations of the new products.Source: Sparkle

6% drop or not, this is a 9500GT. NINETY FIVE HUNNERD GT.

those things dont run that bloody hot in the first place, i've seen passive ones run cooler than that.

did the 5-6 degrees in GPU temp make all this, got a good gpu cooler and the title about 15-20 temp decrease

This is as bad as Snake Milk or Crystals....
They state that current heatsinks made of aluminium and copper carry heat "electrically", wheras this stuff carries heat via phonons.
Heat IS phonons!! There is no such thing as electrical heat tranfer, thats complete bullsh!t. This just has better thermal conductivity than copper or aluminium, which has nothing to do with electrical heat transfer, only phonons.

And how DID they get a 9500 GT up to 88C?? Put it in a room with ambient temps are 60C??

dont forget to look at the pic they provided, you can clearly see a fan. 80C + with a FAN

Or, you could just open a window. I got all excited when I saw that the computer industry was using diamond in heatsinks, but I grew ever more dissapointed when I read "sputtering", and "which plate a Diamond-like Carbon (DLC) membrane on the surface of video cards cooling fins". So basically they're pissing all over the video card and the fins of some heatsink with some kind of synthetic diamond-LIKE substance.

1. Why "plate a Diamond-like Carbon (DLC) membrane on the surface of video cards"? Wouldn't showering a video card in fake diamond-carbon crap be bad for it? When I apply thermal paste to my video cards I only apply it to the GPU (and memory if nescessary), I don't dump the whole tube all over the circuit board. If this is supposed to be a material that helps in thermal trasfer, why waste it on parts that are never going to be touched by the heatsink anyway?

2. Why waste it on the fins? Again I don't put thermal paste anywhere on my heatsink, except maybe the base if you perfer to put it on the base of the heatsink instead of the component being cooled, do you? Ah yes lets dump this thermal paste all over my shiny new Tuniq Tower (if I had one... I wish) :rolleyes:

3. "it can protect the radiator metal from scratching". What? I would RATHER have my "radoator metal" scratched up all to hell and back. That would increace surface area. The only thing I DON'T want scratched is the base of the heatsick, becase that would DECREACE the total surface area with direct contact with the component being cooled.
