The Austrian company Noctua is not a manufacturer that quickly implements all its conceptual developments, but this is compensated by the quality of engineering calculations in the preparation of serial products. Last year, she showed a prototype of a passive radiator weighing one and a half kilograms, but the heavyweight will go into series only by the end of this year.
This is reported by the resource with reference to the comments of Noctua representatives. . Will the serial version repeat the characteristics and configuration prototype, is not specified, there is no data on the price of the product. The prototype weighing one and a half kilograms used a base with six copper heat pipes that pierced twelve aluminum plates 1,5 mm thick, removed from each other at a decent distance. This was done to facilitate air convection, since the radiator must be able to handle 120W of thermal energy without external blowers. On the demo stand, the prototype easily cooled an eight-core Intel Core i9-9900K processor.
Case fans present in the neighborhood can increase the performance ceiling of the cooling system up to 180 watts. According to Noctua representatives, when designing the serial version of such a radiator, the emphasis will be on design efficiency, and not on appearance. Surely you will have to work on the mass of the product, since hanging one and a half kilos on the motherboard is not so safe. If it fails to introduce a novelty this year, it may be slightly delayed until the beginning of the next, as the source explains.
