Up for sale is a 3-pack of genuine, fully sleeved Noctua Low-Noise Fan Adapters. Designed to sit between your PC fan and power source, these adapters use integrated inline resistors to safely drop fan speed and significantly reduce system acoustics—perfect for taming high-RPM or Noctua Redux series fans.

Item Condition: Genuine Noctua adapters removed from original fan bundles (loose, unused/like-new condition; no retail packaging included).

Compatibility Note: These are the exact same individual adapter cables provided in Noctua's retail NA-SRC7 (PWM), NA-SRC10 (3-Pin), and NA-SRC12 (3-Pin) accessory sets.

Please select your preferred set from the listing options:

Option 1: 3x NA-RC7 (4-Pin PWM L.N.A.)

• Connector: 4-Pin PWM (passes through full PWM signal)

• Function: Standard Low-Noise Adapter for 4-pin PWM fans

• Performance: Reduces maximum fan speed by ~20–30% while retaining dynamic PWM control

Option 2: 3x NA-RC10 (3-Pin L.N.A.)

• Connector: 3-Pin Standard (Voltage-controlled)

• Function: Standard Low-Noise Adapter for 3-pin non-PWM fans

• Performance: ~50 Ω resistor provides a moderate ~20–30% drop in RPM and noise while ensuring clean motor startup

Option 3: 3x NA-RC12 (3-Pin U.L.N.A.)

• Connector: 3-Pin Standard (Voltage-controlled)

• Function: Ultra-Low-Noise Adapter for 3-pin FLX, standard, or ULN series fans

• Performance: High-resistance (~150 Ω) adapter for maximum acoustic reduction, cutting RPM by ~40% or more
