## Summary description

Noctua NA-FK1 is a 120 mm case fan with a 4-pin PWM connector, SSO bearing and 12 V operation. It delivers up to 120.2 m³/h airflow at a maximum 1700 RPM while producing 25.1 dB noise at high speed. Includes mounting kit, Molex peripheral power cable, jumper cable and instruction sheet. Suitable for computer case cooling with MTBF ~150,000 h.

## Long description

The Noctua NA-FK1 is a second fan kit for the NH-U12S redux CPU cooler that enables a push/pull dual-fan configuration. It includes a second NF-P12 redux-1700 PWM fan, anti-vibration pads, fan mounting clips, a 4-pin PWM y-cable and two Low-Noise Adaptors, providing the components needed to increase cooling efficiency or reduce acoustic levels by running two fans at lower speeds.
Advantages
Adding the NA-FK1 delivers modest but measurable improvements in thermal performance (typically around 1–3°C depending on the load) and allows acoustic fine-tuning by splitting the workload across two fans. The included NF-P12 redux-1700 PWM is the same model used on the NH-U12S redux, ensuring compatibility and balanced airflow. The kit’s anti-vibration pads and mounting clips simplify installation while the y-cable and Low-Noise Adaptors enable both automatic PWM control and lower-speed operation.
Suitable for
NH-U12S redux users who want a push/pull dual-fan setup
Systems with higher-end CPUs, heavy turbo usage or overclocking
Builders seeking lower noise levels through reduced fan speeds
Key specifications
Contents: NF-P12 redux-1700 PWM fan, anti-vibration pads, fan mounting clips, 4-pin PWM y-cable, two Low-Noise Adaptors
Fan diameter: 120 mm
Fan speed range (NF-P12 redux-1700 PWM): approx. 450–1700 RPM (PWM)
Compatibility: designed for Noctua NH-U12S redux cooler
Operating voltage: 12 V
How to use
Mount the supplied NF-P12 redux-1700 PWM fan to the NH-U12S redux using the included fan clips and anti-vibration pads to create a push/pull configuration with the pre-installed fan. Connect both fans to the CPU fan header using the provided 4-pin PWM y-cable to allow automatic speed control, or use the Low-Noise Adaptors to lower the maximum fan speed for quieter operation. Ensure the airflow direction matches between the two fans for optimal performance.
Usage recommendations
For best results, use the NA-FK1 in systems with medium to high thermal loads or when acoustic reduction is required; monitor temperatures after installation to confirm the expected 1–3°C improvement and adjust fan control settings or Low-Noise Adaptors as needed.
