Noctua NF-S12B redux-1200, High Performance Cooling Fan, 3-Pin, 1200 RPM (120mm, Grey)

Bottom line: The Noctua NF-S12B redux-1200 ($16.95 on Amazon as of 2026-10-21 04:20 UTC): 18.1 dB(A) at full 1200 RPM keeps it quiet without manual tuning; main trade-off: 3-pin only, so no PWM control from a 4-pin motherboard header.

Pros & Cons

Pros

  • ✓ 18.1 dB(A) at full 1200 RPM keeps it quiet without manual tuning
  • ✓ Airflow-optimised blades tuned for low-resistance case intake and exhaust
  • ✓ Rated >150,000 hours MTTF, so it outlasts most builds it goes into
  • ✓ Grey redux colorway avoids Noctua's usual beige-and-brown palette

Cons

  • ✗ 3-pin only, so no PWM control from a 4-pin motherboard header
  • ✗ Fixed 1200 RPM with no low-noise adaptor included in the box
  • ✗ Low-resistance blade design is a poor match for thick radiators
  • ✗ Anti-vibration mounts and splitters are sold separately as accessories

Manufacturer description

This 120x120x25 mm 12V fan spins at a fixed 1200 RPM and measures 18.1 dB(A), which puts it in genuinely quiet territory for a fan moving this much air. The blade geometry is tuned for low airflow resistance, so it does its best work as a case intake or exhaust and in chassis ventilation roles rather than crushed against a dense radiator fin stack. You get a 3-pin Molex connector, so speed control comes from your motherboard's voltage-based fan headers or from Noctua's optional NA-SRC10 Low-Noise Adaptors rather than from PWM. The original NF-S12B design collected more than 100 awards and…
