Faster GPUs need better cooling
Generally when we see NVIDIA bragging about new tech it tends to be a new GPU or other advancement in hardware. I can’t recall ever seeing NVIDIA talking specifically about new cooling tech that was coming to market in future GPUs. However, cooling tech is a majorly important part of bringing new performance GPUs to market.

As video cards and the GPUs on the cards get more powerful, they need more power. More power means that the cards produce more heat. More heat means that the cards need larger cooling solutions with fans that run faster, which in turn produces more noise. There also comes a point where air simply can’t cool the GPU sufficiently and we reach a place where GPUs can get no faster without going to alterative cooling like water or other tech.
NVIDIA is showing off new cooling tech that uses what looks like a normal fan and heat sink on the outside. The card showing the new cooling tech appears to have the standard dual slot design we are used to seeing on most performance cards today. Under that common looking shroud and fan lies a heat sink that uses new tech called vapor chamber technology.
The vapor chamber cooling technology allows the new GPU to not only run cooler, meaning it can be made to run faster, but it is also quieter as well. Any gamer that has sat beside a gaming machine with one or more high-end video cards inside running at full tilt on a graphically challenging video game will tell you the PC can get very loud. Making cooling tech that is quieter and cools better is a huge gain for the enthusiast and gamer.
From the images on Rumorpedia, it appears that the copper section of the new heat sink has a liquid inside that evaporates as it takes in heat from the GPU and then the liquid condenses and returns to the bottom of the cooler for the cycle to start again. It's some pretty slick tech for sure that promises to perform better, yet run quieter than existing cooling systems on NVIDIA video cards. We don’t know at this point what video card will turn up with the technology first or when it will hit the market. If NVIDIA is already talking about the tech, it should be sooner rather than later when we can all get our hands on this tech. I wonder how well the new cooling tech will work for overclockers.
