Noctua NF-A14x25 G2 PWM Sx2-PP, Dual Fan Set for Push-Pull and Side-by-Side Applications (Brown)

Bottom line: The Noctua NF-A14x25 G2 PWM Sx2-PP ($84.95 on Amazon as of 2026-10-21 04:20 UTC): Two fans offset ~25rpm to prevent acoustic interaction; main trade-off: brown/beige colorway clashes with most build themes.

SpecPicks Verdict

SpecPicks scored Noctua NF-A14x25 G2 PWM Sx2-PP using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. Noctua's PC & gaming hardware lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for PC & gaming hardware of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

  • Dedicated dual fan set with two NF-A14x25 G2 PWM 140x25mm fans that are slightly off-set in speed (+/- ~25rpm) in order to avoid undesired acoustic interaction phenomena

  • Ideal choice for push-pull applications as well as situations where two fans are operating side by side (280mm water cooling radiators, case intake or exhaust fans, etc.)
  • Includes anti-vibration mounts, anti-vibration gaskets for tighter seal on radiators, fan screws, Low-Noise Adaptors (LNA), extension cables and y-cable for running two fans on the same header
  • Trusted Noctua quality with premium-grade SSO2 bearing (MTTF > 150,000 h), safety certifications from UL and TÜV, protected against reverse polarity, over voltage and over current (short-circuits)
