Pictures may differ from actual products
The Noctua NF-A14x25r G2 PWM Sx2-PP is a kit comprising two NF-A14x25r G2 PWM 140 mm fans for push-pull cooling of heatsinks such as the NH-D15(S) or NH-U14S. The two fans included in the Sx2-PP kit have been set with a speed offset of approximately 25 RPM.

140 mm push-pull fan kit
The Noctua NF-A14x25r G2 PWM Sx2-PP is a kit comprising two NF-A14x25r G2 PWM 140 mm round frame fans for push-pull cooling of heatsinks such as the NH-D15(S) or NH-U14S. The two NF-A14x25r G2 PWM fans included in the Sx2-PP kit have been set with a speed offset of approximately 25 rpm to reduce vibration and cyclic hum. Such fine-tuning was made possible by the etaPERF fan motor and its NE-FD6 integrated circuit, which allow extremely fine speed adjustment.
Highlights
- The NF-A14x25 G2 features an innovative Progressive-Bend turbine with Flow Acceleration Channels and winglets. Its 9 blades, which tend to face backwards on the hub side, curve progressively outwards at the tip.
- The Centrifugal Turbulator hub and its specific design improve the cohesion of flows in the hub area. In addition, its movement exerts a centrifugal force that moves the air away from the hub, and therefore away from the area that is less efficient given the low rotation speeds.
- The winglets (curves at the tips of the blades) reduce the vortex phenomena at the tips of the blades generated by the pressure differences between the suction faces of the blades.pressure differences between the suction and extraction sides, but can reduce efficiency given the large fluid displacements in high-speed zones.
- Integral anti-vibration mounts, made from extra-flexible silicone, limit the transmission of vibrations while ensuring perfect compatibility with standard screws and fastening systems.
- Protected against reverse polarity, overvoltage and overcurrent (short circuits), the fan is suitable for use in harsh electrical environments.
