Noctua NA-FK1 Redux, Second Fan Upgrade Kit for NH-U12S Redux Cooler
The NA-FK1 is a second fan kit for the NH-U12S redux CPU cooler. Upgrading it to a push/pull-style dual-fan setup makes it possible to further improve cooling performance or to reduce noise levels by having two fans running at lower speeds. The kit includes a second NF-P12 redux-1700 PWM fan, anti-vibration pads, fan mounting clips, a 4-pin PWM y-cable as well as two Low-Noise Adaptors – everything you need to boost the efficiency of your NH-U12S redux! Enhanced cooling performance Adding a second NF-P12 redux-1700 PWM fan to the NH-U12S redux makes it possible to further improve cooling performance by around 1-3°C, depending on the application. As a rule of thumb, the gains are bigger the higher the heat load, so the NA-FK1 is particularly attractive for higher-end CPUs, extensive turbo use or overclocking. NF-P12 redux-1700 PWM The NF-P12 redux-1700 PWM fan included with the NA-FK1 is the same high-quality unit that comes pre-installed on the NH-U12S redux CPU cooler, so it’s a perfect match for a push/pull-style dual-fan setup. Supporting PWM for automatic speed control, it can run near silent most of the time and provide massive performance when necessary. Lower noise levels and acoustic fine-tuning The NA-FK1 can not only be used to enhance cooling performance, but also to lower noise levels: by letting both fans run at reduced speeds, either via automatic PWM control using the supplied y-cable or via the included Low-Noise Adaptors, the NH-U12S redux can operate more quietly while maintaining the same level of performance.

Product Features
- Upgrades the NH-U12S redux to a push/pull dual-fan configuration for improved performance or lower noise levels when running both fans at lower speed
- Can reduce temperatures by 1-3C, especially on higher heat-loads such as during turbo use, on overclocked systems or higher TDP processors
- Second high-quality NF-P12 redux-1700 PWM fan supports automatic speed control via the motherboard, can provide massive airflow at load and run whisper-quiet at idle
- Low-Noise Adaptors allow the maximum fan speed to be reduced from 1700 to 1300rpm for near-silent operation
- Includes 1x NF-P12 redux-1700 PWM fan, 4 anti-vibration pads, 1 pair of fan mounting clips, 1x 4-pin PWM y-cable and 2x Low-Noise Adaptors
