Sapphire is releasing its next generation of graphic card coolers based on liquid metal which is even more efficient than water cooling. The liquid metal will flow through the copper pipes circled with electromagnetic phenomenon to cool down the card. Some early testing showed that prototype cooled Radeon X850XT PE card to just 12 Celsius. At this time liquid metal cooling will have some fans on while a final design might be fanless. Sapphire will have this product ready in July and will launch many other SKUs based on it.
This technology is actually developed by nanoCoolers and here are some detailed information :

"The cooling loop consists of liquid metal as the working fluid, a heat source exchanger, an ambient heat exchanger, an electromagnetic pump, and interconnecting tubing. The liquid metal has significant advantages over other single phase liquid solutions. The thermal and physical properties of the material give it the ability to cool extremely high heat fluxes. With its very low vapor pressure, the boiling point of the material is in excess of 2000°C. This provides the capability to cool extremely high power densities without the liquid-metal changing phase, removing power density as the limiting factor in cooling performance. The liquid metal is non-flammable, non-toxic and environmentally friendly. As a metal, the liquid is both highly thermally conductive and highly electrically conductive. The thermal conductivity makes it ideal for heat removal and dissipation. The electrical conductivity enables the use of electromagnetic pumps to propel the liquid."
