Noctua presents next-generation NF-A12x25 120mm fan, 140mm adaptor and redux line NF-P12
Noctua today presented its much-anticipated next-generation 120x25mm A-series fan and the complementary NA-SFMA1 adaptors that allow it to be used on 140mm based watercoolers. The new NF-A12x25 is the first fan made of Noctua’s novel Sterrox® LCP material and integrates the company’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance. While the NF-A12x25 becomes the new flagship model in the 120mm range, the classic NF-P12 will be reissued in the streamlined, more affordable redux line.
