Noctua presented two promising developments that can revive the market of cooling systems for CPUs and graphics cards.  However, while it is a prototype for CPU coolers - this cover for the heatsink from the "diamond dust" with high thermal conductivity and a cooler with active noise cancellation. The use of diamond films in the computer market first tried Sparkle company  in 2009.  Then this brand was introduced in the GeForce 9500 GT to the radiator on diamonds, the effectiveness of which has allowed to play without a heatsink covering 5 degrees Celsius.  The idea of development is to reduce the thermal resistance of the contact area and the heat dissipation radiator cover processor.  Diamond-like film, as a material made use of polycrystalline diamond film, rather than single crystal diamonds which are mad to have a better thermal conductivity than conventional materials.  In experiments Noctua talking about a 25% improvement in thermal conductivity values to 500 W / (m * K). Unfortunately, even the single-crystal diamonds for their production requires a very complex conditions, above all - very high temperatures, which limits their distribution.  In the words of Noctua, the use of a coating of diamond dust would raise the cost of coolers by 10-20 euros.   Another prototype Noctua - cooler with active noise cancellation system (Active Noise Cancellation, ANC) - we came across on the same Computex, just a year ago .  Now the company has built a system in a cooler NF-A14 with a 140-mm fan.  Obviously, the effect of noise on it should appear more clearly than in last year's prototype based on Noctua NF-F12.  In fact before us almost finished a commercial sample.  Microphone for determining the acoustic noise is built into the tower from the radiator, and the design looks solid. The system works in creating artificial noise impellers in antiphase with the noise of the working (an effect of noise suppression).  For this purpose the magnets embedded in the impeller, and on the perimeter of rotation looped coil with electromagnets.  Determining the spectrum of natural noise, a special controller, is also a built-in cooler, makes the impeller generate noise cancelling with the amplitude of vibration to 0.1 mm.   Related Products :
