Noctua says these new fans will be twice as good as their existing ones; the company showed at Computex 2017 how a single A-series fan achieved identical temperatures to a setup which used two NF-F12 fans on the same processor, workload, and heatsink. And you thought the NF-F12 were good already, right? There's no actual release date for now, but there's a teaser image of the packaging doing the rounds already - and if that's that far along finished, then we're certainly not that far away from release. Here's hoping pricing will be competitive - but perhaps it needn't be, considering the expected performance - and the fact that Sterrox, the compound used in their manufacturing, is four times more expensive than common PBT.
