Noctua NF-F12 iPPC 3000 PWM Cooling Case Fan w/Focused Flow and SSO2 Bearing NF-F12 industrialPPC-2000 provides a significant performance boost over the 1500rpm retail version. Combined w/ the industrialPPC series' robust polyamide construction & adv. protection features makes the fan ideal for challenging industrial applications. Noctuid'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. While the standard NF-F12 is one of the most energy efficient 1500rpm 120mm fans on the market, the industrialPPC version's three-phase motor provides a further 10% reduction in power consumption when compared at 2000rpm.
