渐进弯曲叶轮
NF-A12x25 G2 具有独特的渐进式弯曲叶轮,带有流量加速通道和尖端翼片。它的九个叶片向后掠过轮毂,并逐渐向前弯曲。与离心式涡轮轮毂协同工作,这种设计不仅有助于将更多空气推向效率更高的外叶片区域,而且还确保了整个叶片跨度的最大拉升力和接近均匀的负载。

SSO2 轴承
NF-A12x25 G2采用经过进一步优化的 Noctua 著名的经过时间考验的第二代SSO轴承。使用SSO2,后磁铁更靠近轴线,以提供更好的稳定性,精度和耐用性。

微距的尖端间隙
NF-A12x25 G2的叶尖间隙(扇叶尖端与扇框内侧之间的距离)仅为0.5mm,创下了历史新高。这一雄心勃勃的设计通过减少通过叶轮和扇框之间间隙的泄漏流量,帮助NF-A12x25 G2更有效地对抗背压,如水冷散热器或风冷散热器等等上的背压。

双风扇组合,可吸气吹气并排使用
为了避免不希望的声学相互作用现象,将两个速度进行微调+/-~50rpm的NF-A12x25 G2 PWM风扇捆绑在一起,Sx2 PP套件是吸气吹气式配置以及两个风扇并排运行的理想选择,例如在240和360mm水冷散热器上或其他典型的散热应用中。
