Noctua NA-FK1 Redux Second-Fan Upgrade Kit for NH-U12S

The Noctua NA-FK1 Redux Second-Fan Upgrade Kit 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.

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.

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.

6-year manufacturer’s warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy, the NF-P12 redux unit that comes with the NA-FK1 set features an MTTF rating of more than 150,000 hours. The entire package comes with a full 6-year manufacturer’s warranty.
