This is the second generation of the iconic NH-D15 super cooler. There are not many changes, but it’s still a long time to wait for the release
Noctua first showed a new generation of CPU cooler NH-D15.
Outwardly, the cooler has changed very little, so they decided not to change the name. But, for example, there were eight heat pipes against six in the first generation. In addition, the gap between the ribs was reduced from 1.9 to 1.6 mm.
Two new-generation 140mm fans will be responsible for airflow, details of which are not yet available. All of this combined should make the iconic cooler a bit more performant, although now, almost 10 years after its release, it is still one of the best-performing CPU coolers on the market.
Despite the demonstration, the release of the novelty is still far away: Noctua is going to release the cooler only next year.
