Noctua NF-A14 14cm PWM Fan, IP67, 31.5dB, 12V, Compatible with Server, Desktop, Industrial Equipment

Features

• 2000rpm industrialPPC version : Thanks to its elevated 2000rpm top speed, the NF-A14 industrialPPC-2000 provides a significant performance boost over the 1500rpm retail version. Combined with the industrialPPC series' robust polyamide construction and advanced protection features, this makes the fan ideal for challenging industrial applications.
• Three-phase motor design : While most axial fans use single-phase motors with 4 slots, Noctua's industrialPPC fans feature a three-phase design with 6 slots, which provides smoother transitions between the slots and thus allows for even higher running smoothness, further reduced vibrations and unprecedented energy efficiency.
• Class-leading energy efficiency : While the standard NF-A14 is one of the most energy efficient 1500rpm 140mm fans on the market, the industrialPPC version's three-phase motor provides a further 10% reduction in power consumption when compared at 2000rpm.
• Fibre-glass reinforced polyamide construction : Both the impeller and the frame of Noctuas industrialPPC fans are made entirely from fibre-glass reinforced polyamide. This material can withstand temperatures up to 140C and makes the fans even more robust and break-proof than Noctuas standard fibre-glass reinforced PBT fans.
• Certified IP67 water- and dust protection : The motor and PCB of the IP67 version are completely cast in a special, highly heat conductive resin that combines thoroughgoing protection and effective motor heat dissipation. Complying with the ingress protection rating IP67, this fan is not only fully dust tight but also completely waterproof up to 1m water depth.
