Noctua NF‑A14x25r G2 PWM Sx2‑PP 140 mm Fan Set
The Noctua NF‑A14x25r G2 PWM Sx2‑PP 140 mm Fan Set includes two round‑frame case fans configured for push‑pull operation, precisely speed‑offset to eliminate acoustic beat frequencies and deliver elite cooling performance.
Push‑Pull Dual Set with Precision Acoustic Tuning
Speed‑Offset Fans to Prevent Beat Frequencies
This bundled set pairs two NF‑A14x25r G2 PWM fans with a ±25 RPM offset—one slightly slower (PPA), one faster (PPB)—to avoid unwanted harmonic interference in push‑pull setups, ensuring smooth acoustic performance.
etaPERF™ Motor with NE‑FD6 & SupraTorque™
The motors leverage Noctua’s etaPERF™ design and NE‑FD6 driver IC featuring Smooth Commutation Drive 2 and SupraTorque™ for precise speed control and reliable performance under airflow resistance.
Next‑Gen Aerodynamics & Build
Progressive‑Bend Impeller with Flow Acceleration & Winglets
Each fan includes a Progressive‑Bend impeller with winglets and Flow Acceleration Channels, optimized by a Centrifugal Turbulator hub—delivering superior static pressure and airflow efficiency.
Ultra‑Tight Tip Clearance & Sterrox® LCP Construction
Engineered with just 0.7 mm clearance between blade tips and frame, and crafted from Sterrox® liquid‑crystal polymer, this fan maximizes efficiency and durability even under constrained airflow conditions.
