Noctua NA-FK1 redux
Noctua NA-FK1 redux
The Noctua NA-FK1 redux fan kit is designed to upgrade the NH-U12S redux cooler to a push/pull configuration. It improves cooling performance under high thermal loads, such as during demanding CPU tasks or overclocking. The kit ensures stable operation even during intensive applications where an optimal temperature is key to long-term performance. The fans can run at lower speeds, controlled automatically via PWM or by using the included Low-Noise Adaptors, achieving quiet operation without sacrificing cooling performance.
Key features of the Noctua NA-FK1 redux PC fan
- Two fans for a push/pull configuration
- Improves cooling by 1–3°C
- Option to reduce noise at lower speeds
- Compatible with the NH-U12S redux
- PWM support for automatic speed control
- Quiet operation under normal load
Improved cooling
This change is most noticeable under heavy loads, such as in turbo mode or when overclocking, where more effective heat dissipation is needed. Adding a second fan improves cooling performance by 1–3°C, which is useful for high-performance processors. The kit ensures stable operation even during intensive applications where an optimal temperature is key to long-term performance.
Compatibility and features
The NA-FK1 redux kit is fully compatible with the NH-U12S redux cooler, ensuring seamless integration. This fan uses PWM for automatic speed control, which means it runs quietly under normal load but can also handle intensive cooling when needed. The fan is identical to the one pre-installed on the cooler, making it the ideal addition for a dual-fan configuration.
